A practical, catalytic entry to α,α,α-trisubstituted (α-tertiary) primary amines by C-H functionalization has long been recognized as a critical gap in the synthetic toolbox. The authors report a simple and scalable solution to this problem that does not require any in situ protection of the amino group and proceeds with 100% atom-economy. The authors’ strategy, which uses an organic photocatalyst in combination with azide ion as a hydrogen atom transfer (HAT) catalyst, provides a direct synthesis of α-tertiary amines, or their corresponding γ-lactams. The authors anticipate that this methodol. will inspire new retrosynthetic disconnections for substituted amine derivatives in organic synthesis, and particularly for challenging α-tertiary primary amines.

Rummelt, Stephan M.;Peterson, Paul O.;Zhong, Hongyu;Chirik, Paul J. research published 《 Oxidative Addition of Aryl and Alkyl Halides to a Reduced Iron Pincer Complex》, the research content is summarized as follows. The two-electron oxidative addition of aryl and alkyl halides to a reduced Fe dinitrogen complex with a strong-field tridentate pincer ligand was demonstrated. Addition of iodobenzene or bromobenzene to (3,5-Me2MesCNC)Fe(N2)2 (3,5-Me2MesCNC = 2,6-(2,4,6-Me-C6H2-imidazol-2-ylidene)2-3,5-Me2-pyridine) resulted in rapid oxidative addition and formation of the diamagnetic, octahedral Fe(II) products (3,5-Me2MesCNC)Fe(Ph)(N2)(X), where X = I or Br. Competition experiments established the relative rate of oxidative addition of aryl halides as I > Br > Cl. A linear free energy of relative reaction rates of electronically differentiated aryl bromides (ρ = 1.5) was consistent with a concerted-type pathway. The oxidative addition of alkyl halides such as Me-, isobutyl-, or neopentyl halides was also rapid at room temperature, but substrates with more accessible β-H positions (e.g., 1-bromobutane) underwent subsequent β-hydride elimination. Cyclization of an alkyl halide containing a radical clock and epimerization of neohexyl iodide-d2 upon oxidative addition to (3,5-Me2MesCNC)Fe(N2)2 are consistent with radical intermediates during C(sp3)-X bond cleavage. Importantly, while C(sp2)-X and C(sp3)-X oxidative addition produces net two-electron chem., the preferred pathway for obtaining the products is concerted and stepwise, resp.

Despite the therapeutic relevance of δ-containing γ-aminobutyric acid type A receptors (GABAARs) and the need for δ-selective compounds, the structural determinants for the mode and mol. site of action of δ-selective pos. allosteric modulator imidazo[1,2-a]pyridine DS2 remain elusive. To guide the quest for insight, we synthesized a series of DS2 analogs guided by a structural receptor model. Using a fluorescence-based fluorometric imaging plate reader membrane potential assay, we found that the δ-selectivity and the pharmacol. profile are severely affected by substituents in the 5-position of the imidazopyridine core scaffold. Interestingly, the 5-Me, 5-bromo, and 5-chloro DS2 analogs, 30, 35, and 36, were shown to be superior to DS2 at α4β1δ as mid-high nanomolar potency δ-selective allosteric modulators, displaying 6-16 times higher potency than DS2. Of these, 30 also displayed at least 60-fold selectivity for α4β1δ over α4β1γ2 receptor subtypes representing a potential tool for the selective characterization of δ-containing GABAARs in general.

For the Fe-complexes an electron withdrawing NO2 or CF3 group attached to the 5-position of the quinoline unit increased the catalytic current, but only with a simultaneous increase of the overpotential. However, when a pyrene moiety was attached to the dipicolylamine unit of the ligand, the overpotential decreased with concomitant increase of the catalytic current. Although the manganese complexes showed no reversible formation of a mol. catalytically active species for water oxidation, the variations of the ligand scaffold affected largely the same trends in their electrochem. behavior.

Remeur, Camille;Kelly, Christopher B.;Patel, Niki R.;Molander, Gary A. research published 《 Aminomethylation of Aryl Halides Using α-Silylamines Enabled by Ni/Photoredox Dual Catalysis》, the research content is summarized as follows. In the presence of the ruthenium photocatalyst [Ru(bipy)3](PF6)2 and the nickel catalyst [Ni(dtbpy)(OH2)4]Cl2 (dtbpy = 4,4′-di-tert-butyl-2,2′-bipyridine), aryl bromides and iodides such as 4-bromobenzonitrile underwent chemoselective aminomethylation reactions with aminomethylsilanes such as 1-(dimethylphenylsilylmethyl)piperidine in DMF under irradiation with blue LED for 24-36 h at ambient temperature to yield benzylic amines such as 4-(1-piperidinylmethyl)benzonitrile in 41-70% yields. The low oxidation potential of the silylmethyl amines enabled facile single electron transfer (SET) oxidation of the amine followed by rapid desilylation; the resultant α-amino radicals were competent to undergo nickel-mediated cross-coupling with aryl bromides and iodides.

Gaining chem. control over the thermodn. and kinetics of photoexcited states is paramount to an efficient and sustainable utilization of photoactive transition metal complexes in a plethora of technologies. In contrast to energies of charge transfer states described by spatially separated orbitals, the energies of spin-flip states cannot straightforwardly be predicted as Pauli repulsion and the nephelauxetic effect play key roles. Guided by multireference quantum chem. calculations, we report a novel highly luminescent spin-flip emitter with a quantum chem. predicted blue-shifted luminescence. The spin-flip emission band of the chromium complex [Cr(bpmp)2]3+ (bpmp = 2,6-bis(2-pyridylmethyl)pyridine) shifted to higher energy from ca. 780 nm observed for known highly emissive chromium(III) complexes to 709 nm. The photoluminescence quantum yields climb to 20%, and very long excited state lifetimes in the millisecond range are achieved at room temperature in acidic D2O solution Partial ligand deuteration increases the quantum yield to 25%. The high excited state energy of [Cr(bpmp)2]3+ and its facile reduction to [Cr(bpmp)2]2+ result in a high excited state redox potential. The ligand′s methylene bridge acts as a Bronsted acid quenching the luminescence at high pH. Combined with a pH-insensitive chromium(III) emitter, ratiometric optical pH sensing is achieved with single wavelength excitation. The photophys. and ground state properties (quantum yield, lifetime, redox potential, and acid/base) of this spin-flip complex incorporating an earth-abundant metal surpass those of the classical precious metal [Ru(α-diimine)3]2+ charge transfer complexes, which are commonly employed in optical sensing and photo(redox) catalysis, underlining the bright future of these mol. ruby analogs.
