Benzoylhydrazone Schiff base-ligated three new ONO pincer-type palladium(II) complexes, [(PdL1(PPh3)] (1), [(PdL2(PPh3)] (2), and [(PdL3(PPh3)] (3), were synthesized by the reaction of the respective ligand, N-(2-hydroxybenzylidene)benzohydrazide (HL1), N-(2-hydroxy-3-methoxybenzylidene)benzohydrazide (HL2), or N-(5-bromo-2-hydroxybenzylidene) benzohydrazide (HL3), with Pd(OAc)(2) and PPh3 in methanol and isolated as air-stable reddish-orange crystalline solids in high yields (78%-83%). All three complexes were fully characterized by elemental analysis, Fourier-transform infrared spectroscopy, UV-Visible, H-1 nuclear magnetic resonance (NMR), C-13{H-1} NMR, and P-31{H-1} NMR spectroscopic studies. The molecular structure of all three complexes was established unambiguously by single-crystal X-ray diffraction studies which revealed a distorted square planar geometry of all three complexes. The ONO pincer-type ligands occupied three coordination sites at the palladium, while the fourth site is occupied by the monodentate triphenylphosphine ligand. The catalytic potential of all three complexes was explored in the carbonylative Suzuki coupling of aryl bromides and iodides with arylboronic acids to yield biaryl ketones, using CHCl3 as the source of carbonyl. The reported protocol is convenient and safe as it obviates the use of carbon monoxide (CO) balloons or pressured CO reactors which are otherwise needed for the carbonylation reactions. The methodology has been successfully applied to the synthesis of two antineoplastic drugs, namely, phenstatin and naphthylphenstatin, in good yields (81% and 85%, respectively). Under the optimized reaction conditions, complex 2 exhibited the best catalytic activity in the carbonylative Suzuki couplings. The reported catalysts have wide reaction scope with good functional group tolerance. All catalysts could be retrieved from the reaction after completion and recycled up to three times with insignificant loss in the catalytic activity.

Safety of Phenyl(pyridin-2-yl)methanone. I found the field of Chemistry very interesting. Saw the article Photocatalytic Radical Aroylation of Unactivated Alkenes: Pathway to beta-Functionalized 1,4-, 1,6-, and 1,7-Diketones published in 2019.0, Reprint Addresses Ngai, MY (corresponding author), SUNY Stony Brook, Dept Chem, Stony Brook, NY 11794 USA.. The CAS is 91-02-1. Through research, I have a further understanding and discovery of Phenyl(pyridin-2-yl)methanone.

We report the development of a photocatalytic strategy for the synthesis of beta-functionalized unsymmetrical 1,4-, 1,6-, and 1,7-diketones from aroyl chlorides and unactivated alkenes at room temperature. The mild reaction conditions not only tolerate a wide range of functional groups and structural moieties, but also enable migration of a variety of distal groups including (hetero)arenes, nitrile, aldehyde, oxime derivative, and alkene. The efficiency of chirality transfer, factors that control the distal-group migration, and synthesis of carbocycles and heterocycles from the diketones are also described. Mechanistic studies suggest a reaction pathway involving a photocatalytic radical aroylation of unactivated alkenes followed by a distal-group migration, oxidation, and deprotonation to afford the desired diketones.

Triazole-based ligands, tris (triazolyl)methanol (Htbtm), bis (triazolyl)-phenylmethanol (Hbtm), and phenyl (pyridin-2-yl)(triazolyl)methanol (Hpytm), with differences in ligand denticity (i.e., bidentate and tridentate) and type of N donors (i.e., triazole and pyridine) were functionalized onto a silica support to produce the corresponding SiO2-L (L = tbtm, btm, pytm). Subsequent reactions with Pd (CH3COO)(2) in CH2Cl2 yielded Pd/SiO2-L. ICP-MS reveals that Pd loadings are higher with increased N loadings, resulting in the following trend: Pd/SiO2-tbtm (0.83 mmol Pd g(-1)) > Pd/SiO2-btm (0.65 mmol Pd g(-1)) ~ Pd/SiO2-pytm (0.63 mmol Pd g(-1)). Meanwhile, TEM images of the used Pd/SiO2-L catalysts after the first catalytic cycle show that the mean size of Pd NPs is highest with Pd/SiO2-pytm (8.5 +/- 1.5 nm), followed by Pd/SiO2-tbtm (6.4 +/- 1.6 nm) and Pd/SiO2-btm (4.8 +/- 1.3 nm). Based on TONs, catalytic studies toward aerobic oxidation of benzyl alcohol to benzaldehyde at 60 degrees C in EtOH showed that Pd/SiO2-pytm possessed the most active surface Pd(0) atoms, most likely as a result of more labile properties of the pyridine-triazole ligand compared to tris- and bis (triazolyl) analogs. ICP-MS and TEM analysis of Pd/SiO2-btm indicate minimal Pd leaching and similar average Pd NPs sizes after 1(st) and 5(th) catalytic runs, respectively, confirming that SiO2-btm is an efficient Pd NPs stabilizer. The Pd/SiO2-btm catalyst was also active toward aerobic oxidation of various benzyl alcohol derivatives in EtOH and could be reused for at least 7 reaction cycles without a significant activity loss.

Photoredox catalysis in recent years has manifested a powerful branch of science in organic synthesis. Although merging photoredox and metal catalysts has been a widely used method, switchable heterogeneous photoredox catalysis has rarely been considered. Herein, we open a new window to use a switchable heterogeneous photoredox catalyst which could be turned on/off by changing a simple stimulus (O-2) for two opponent reactions, namely, oxidative and protodecarboxylation. Using this strategy, we demonstrate that Au@ZnO core-shell nanoparticles could be used as a switchable photocatalyst which has good catalytic activity to absorb visible light due to the localized surface plasmon resonance effect of gold, can decarboxylate a wide range of aromatic and aliphatic carboxylic acids, have multiple reusability, and are a reasonable candidate for synthesizing both aldehydes/ketones and alkane/arenes in a large-scale set up. Some biologically active molecules are also shown via examples of the direct oxidative and protodecarboxylation which widely provided pharmaceutical agents.

With a one-pot assembly method, two copper-containing Keggin-type polyoxometalate-based metal-organic frameworks (POMOFs), i.e., [Cu-6(I)(trz)(6){PW12O40}(2)] (HENU-2, HENU = Henan University; trz = 1,2,4- triazole) and [Cu-3(I)(trz)(3){PMo12O40}] (HENU-3), were successfully prepared and structurally characterized. These two compounds, which are generated by the extension of a crown-like {Cu-6(trz)(6)} macrocycle-based sandwich-type structural unit, possess identical noninterpenetration 3D frameworks except for the polyanions difference. Additionally, both of them are assessed as highly effective heterogeneous catalysts in facilitating the oxidation of alkylbenzenes to ketone products in the presence of tert-butyl hydroperoxide. Under optimized conditions, HENU-2 can achieve a 95.2% conversion of diphenylmethane in 20 h with a 100% selectivity toward benzophenone, and it was reused for three runs with constant high activity, which outperforms most POM-based catalysts for this catalytic reaction.

Directed evolution of enzymes for the asymmetric reduction of prochiral ketones to produce enantio-pure secondary alcohols is particularly attractive in organic synthesis. Loops located at the active pocket of enzymes often participate in conformational changes required to fine-tune residues for substrate binding and catalysis. It is therefore of great interest to control the substrate specificity and stereochemistry of enzymatic reactions by manipulating the conformational dynamics. Herein, a secondary alcohol dehydrogenase was chosen to enantioselectively catalyze the transformation of difficult-to-reduce bulky ketones, which are not accepted by the wildtype enzyme. Guided by previous work and particularly by structural analysis and molecular dynamics (MD) simulations, two key residues alanine 85 (A85) and isoleucine 86 (I86) situated at the binding pocket were thought to increase the fluctuation of a loop region, thereby yielding a larger volume of the binding pocket to accommodate bulky substrates. Subsequently, site-directed saturation mutagenesis was performed at the two sites. The best mutant, where residue alanine 85 was mutated to glycine and isoleucine 86 to leucine (A85G/I86L), can efficiently reduce bulky ketones to the corresponding pharmaceutically interesting alcohols with high enantioselectivities (similar to 99% ee). Taken together, this study demonstrates that introducing appropriate mutations at key residues can induce a higher flexibility of the active site loop, resulting in the improvement of substrate specificity and enantioselectivity.

Semicarbazones can exist in two tautomeric forms. In the solid state, they are found in the keto form. This work presents the synthesis, structures and spectroscopic characterization (IR and NMR spectroscopy) of four such compounds, namely the neutral molecule 4-phenyl-1-[phenyl(pyridin-2-yl)methylidene] semicarbazide, C19H16N4O, (I), abbreviated as HBzPyS, and three different hydrated salts, namely the chloride dihydrate, C19H17N4O+center dot Cl-center dot 2H(2)O, (II), the nitrate dihydrate, C19H17N4O+center dot NO3-center dot 2H(2)O, (III), and the thiocyanate 2.5-hydrate, C19H17N4O+center dot SCN-center dot 2.5H(2)O, (IV), of 2-[phenyl({[(phenylcarbamoyl) amino]imino})methyl]pyridinium, abbreviated as [H(2)BzPyS](+)center dot X-center dot nH(2)O, with X = Cl- and n = 2 for (II), X= NO3- and n = 2 for (III), and X = SCN- and n = 2.5 for (IV), showing the influence of the anionic form in the intermolecular interactions. Water molecules and counter-ions (chloride or nitrate) are involved in the formation of a two-dimensional arrangement by the establishment of hydrogen bonds with the N-H groups of the cation, stabilizing the E isomers in the solid state. The neutral HBzPyS molecule crystallized as the E isomer due to the existence of weak pi-pi interactions between pairs of molecules. The calculated IR spectrum of the hydrated [H(2)BzPyS](+) cation is in good agreement with the experimental results.

A novel fluorescent probe, TCF-IPY, has been designed and developed for highly selective and ratiometric detection of GSH based on the extend of the pi-conjugation system of imidazo[1,5-alpha]pyridine IPY-CHO. Upon addition of GSH, TCF-IPY displayed remarkable fluorescence variations (approximate 949-fold ratio changes) from 603 nm to 475 nm, thereby enabling GSH detection in a fine ratiometric manner. Moreover, TCF-IPY exhibited excellent selectivity toward GSH over other biologically related species including Cys and Hcy. The huge blue shifts both in absorption (259 nm) and emission spectra (128 nm), low cytotoxicity, high sensitivity (97 nM) and rapid response (240 s) of TCF-IPY make it a robust molecular tool for endogenous GSH investigation. Furthermore, TCF-IPY was also successfully used for ratiometric imaging of endogenous GSH in living MCF-7 cells and zebrafish.
