Efficient decomposition of formic acid into hydrogen on Pd nanoparticles anchored in amine- pyridine polymer networks without extra additives at ambient condition

Palladium (Pd) is considered as the most promising catalyst for hydrogen production from formic acid decomposition (FAD), but pristine Pd catalysts are less active and readily to perform activity decay by CO poisoning. Thus the modulation of Pd is critical for its application in H-2 production from FAD. Here a Pd/APPNs catalysts by anchoring ca. 2.1 +/- 0.3 nm Pd nanoparticles in the amino-pyridine polymer networks (designated as APPNs) was designed based on so-called metal-support interaction. The strong interaction between Pd and N of amine-pyridine unites was demonstrated by the X-ray photoelectron spectroscopic (XPS) analysis. It suggests the electron transfer between N and Pd, which could lower the d-band center of Pd and further effectively enhance the FAD catalysis performance. The initial FAD TOF value of 512 h(-1) and the activation energy (Ea) of ca. 22.1 kJ mol(-1) give a proper proof for the catalysis enhancement. And the third time FAD run still show a 442 h(-1) TOF, indicating an excellent catalysis stability. In addition, the production analysis by Gas chromatography (GC) show that no CO was detected. This CO-free production was also confirmed through no observation of Surface-enhanced Adsorption Infrared Spectral (SEIRAS) band at 1700-2100 cm(-1) (i.e. the COad species) on Pd/ANNPs surface. This work indicates that direct modification of Pd by the functionalized support (metal-support interaction) could effective enhance the FAD catalysis performance, although further work combined with other tuning means should be push forward.

Heterobimetallic Carbene Complexes Bearing Cyclometalated Ir-III/Rh-III and Mixed NHC boolean AND Py/PPh3 Coordinated Pd-II Centers: Structures and Tandem Catalysis

Heterobimetallic complexes bearing NHC donor ligands are gaining immense popularity in organometallic chemistry and tandem catalysis. It is known that the NHC reacts with Pd-II in the presence of pyridine to yield PEPPSI type complexes and the NHC ligands having ortho-C-H proton easily orthometalate to Ir-III or Rh-III centers. Combining these two methodologies in a stepwise fashion, we present here a series of heterobimetallic Ir-III-Pd-II and Rh-III-Pd-II complexes from a dicarbene donor ligand featuring cyclometalated Ir-III or Rh-III and mixed NHC perpendicular to Py /PPh3 coordinated Pd-II centers. All the heterobimetallic complexes have been structurally characterized by X-ray crystallographic analysis. The heterobimetallic complexes featuring mixed NHC perpendicular to PPh3 coordinated Pd-II centers show better activity in tandem Suzuki-Miyaura/transfer hydrogenation reactions compared to both, the heterobimetallic complexes possessing PEPPSI type Pd(II)centers, and the equimolar mixture of their mononuclear Pd-II and Rh-III or Ir-III counterparts. The heterobimetallic complex featuring cyclometalated Ir-III and mixed NHC perpendicular to PPh3 coordinated Pd-II center shows excellent selectivity for 4-biphenylmethanol (isolated yield: 92 %) in tandem catalysis.

Novel structurally characterized Co(II) metal-organic framework and Cd(II) coordination polymer self-assembled from a pyridine-terminal salamo-like ligand bearing various coordination modes

Two novel structurally characterized Co(II) metal-organic framework (Co(II) MOF) and Cd(II) coordination polymer (Cd(II) CP), [{Co(L)}(2)](n)center dot nCH(3)COCH(3) and [Cd(H2L)(CH3COO)(2)](n) were self-assembled from a newly designed salamo-like ligand H2L bearing double terminal pyridine groups and Co(II) and Cd(II) ions, respectively. In the Co(II) MOF, the Co1 and Co2 ions are six-coordinated octahedron geometries, have similar coordination environments, and are located in the N2O2 cavities of the ligand (L)(2-) units, forming Co1-L and Co2-L parts, respectively. The terminal pyridine N atoms of the Co1-L (or Co2-L) part are connected with Co1-L and Co2-L parts respectively, forming a metal-organic framework with double helix structure in thea-direction and regular channels in the c-direction. In the Cd(II) CP, Cd(II) ion is seven-coordinated single cap triangular prism geometry, did not participate in the coordination of the N2O2 cavity, but coordinated with free acetate in the solution. Two bidentate acetate anions chelate to Cd1 ion, and two Cd1 ions are bridged by O atom of one of the acetate anions to form Cd-2(OAc)(2) unit which was used as the junction point to connect with the terminal pyridine N atoms of H2L. Finally, the coordination polymer with large pore channels was formed. Spectroscopic analyses of H2L and its Co(II) MOF and Cd(II) CP are performed using IR, UV-Vis and fluorescence spectroscopy. TGA analyses show that the Co(II) MOF and Cd(II) CP have good stabilities. Various short-range interactions in the Co(II) MOF and Cd(II) CP are investigated through Hirshfeld surfaces analyses.

A protecting group strategy to access stable lacunary polyoxomolybdates for introducing multinuclear metal clusters

Although metal-containing polyoxomolybdates (molybdenum oxide clusters) exhibit outstanding catalytic properties, their precise synthetic method has not yet been developed. This is mainly because the very low stability of the multivacant lacunary polyoxomolybdates limited their use as synthetic precursors. Here, we present a protecting group strategy in polyoxometalate synthesis and successfully develop an efficient method for synthesising multinuclear metal-containing polyoxomolybdates using pyridine as a protecting group for unstable trivacant lacunary Keggin-type polyoxomolybdate [PMo9O34](9-). Specifically, tetranuclear cubane- and planar-type manganese clusters were selectively synthesised in the polyoxomolybdates using the present method. The importance of this work is that, in addition to being the first practical way of utilizing multivacant lacunary polyoxomolybdates as precursors, this new protecting group strategy will make it possible to produce polyoxometalates with unexplored structures and properties.

Synthesis and bioevaluation of N-(3,4,5-trimethoxyphenyl)-1H-pyrazolo [3,4-b]pyridin-3-amines as tubulin polymerization inhibitors with anti-angiogenic effects

A new series of N-(3,4,5-trimethoxyphenyl)-1H-pyrazolo[3,4-b]pyridin-3-amine derivatives as tubulin polymerization inhibitors were synthesized, and evaluated for the anti-proliferative activities. A structure-activity relationship study revealed that the free amino moiety of 1H-pyrazolo[3,4-b]pyridin-3-amine played an essential role in the anti-proliferative activities. Especially, compound 15c displayed the strongest anti-proliferation against MCF-7 cells with IC50 value of 0.067 +/- 0.003 mu M, and high selectivity over the normal human embryonic lung WI-38 cells with IC50 value of 23.41 +/- 1.53 mu M. Further mechanistic studies revealed that 15c showed strong anti-tubulin polymerization activity, changed the morphology of tubulin, and arrested the cell cycle at the G2/M transition in MCF-7 cells. Molecular docking analysis suggested that 15c well occupied the colchicinebinding pocket of tubulin. Additionally, 15c demonstrated anti-angiogenic activities with blocking the migration, invasion and tube formation, disrupting the newly formed tube, and regulating both MMP-9 and TIMP-1 in HUVEC cells. In summary, our results highlight that compound 15c is a potential antitumor compound that are worthy of further development.

Radiolytic degradation of hydrophilic PyTri ligands for minor actinide recycling

The 2,6-bis[1H-1,2,3-triazol-4-yl]-pyridine (PyTri) chelating unit has already shown promising properties for application to advanced hydrometallurgical processes aimed at recovering minor actinides from highly active raffinate. Radiolytic stability is an undeniable key requirement for chemicals involved in highly radioactive solutions partitioning, since radiolysis can have a huge impact on system safety and performances. In this work, the radiolytic degradation of two hydrophilic PyTri complexing agents was investigated by different analytical techniques. The radiation damage was delivered by a Co-60 source. The main radiation-induced ligand degradation by-products were hypothesized. Unprecedented PyTri ligands radiolytic stability was proved, further recommending their implementation in future partitioning processes.
