Mishiro, Kenji published the artcileEfficiency Enhancement of a Photocatalytic Decarbonylation of an Aminocyclopropenone by Benzothiophene Substitution, Safety of 1,3-Dimethoxybenzene, the main research area is aminocyclopropenone photocatalytic decarbonylation substituent effect benzothiophenyl dehydration condensation.

To improve the efficiency of the photocatalytic decarbonylation of cyclopropenones, the effects of substituents on cyclopropenone were explored. A benzothiophene-substituted aminocyclopropenone exhibited significantly improved decarbonylation efficiency to produce the corresponding ynamine, which worked as a potent dehydration condensation agent. The benzothiophene derivative was applicable to the photocatalytic reaction in the presence of potential excited-state quenchers such as oxygen and anilines. The high catalyst sensitivity would be attributed to the involvement of triplet energy transfer reaction pathway, which was not observed in the reaction with previously reported aminocyclopropenones.

Shon, Jong-Hwa published the artcilePhotoredox catalysis on unactivated substrates with strongly reducing iridium photosensitizers, COA of Formula: C8H10O2, the main research area is aryl halide alkyl hydrodehalogenation iridium photocatalyst.

In this work, the strong bis-cyclometalated iridium photoreductants with electron-rich β-diketiminate (NacNac) ancillary ligands enable high-yielding photoredox transformations of challenging substrates with very simple reaction conditions that require only a single sacrificial reagent. Using blue or green visible-light activation a variety of reactions, which include hydrodehalogenation, cyclization, intramol. radical addition, and prenylation via radical-mediated pathways, with optimized conditions that only require the photocatalyst and a sacrificial reductant/hydrogen atom donor were demonstrated. Many of these reactions involve organobromide and organochloride substrates RX (R = 3-methoxyphenyl, 4-cyanophenyl, {1-[(benzyloxy)carbonyl]piperidin-4-yl}, etc.; X = Br, Cl) which in the past have had limited utility in photoredox catalysis. This work paves the way for the continued expansion of the substrate scope in photoredox catalysis.

Byrne, Liam published the artcileEnantioselective Synthesis of Atropisomeric Biaryls using Biaryl 2,5-Diphenylphospholanes as Ligands for Palladium-Catalysed Suzuki-Miyaura Reactions, HPLC of Formula: 151-10-0, the main research area is biaryl diphenylphospholane preparation; atropisomeric biaryl heterobiaryl preparation; boronic acid aryl bromide asym Suzuki Miyaura palladium catalyst.

Herein, the development of biaryl 2,5-diphenylphospholanes as a new class of C2-sym., monodentate ligands for asym. Suzuki-Miyaura (ASM) reactions is reported. Screening of a series of exemplary phospholanes led to the identification of two ligands that were used to prepare a range of atropisomeric biaryl and heterobiaryl products with good to excellent levels of enantioselectivity (up to 97:3 e.r.) under mild conditions. DFT studies suggest that the formation of a constraining ligand pocket and coordination of one of the biaryl methoxy groups in the optimized ligands to the metal center is crucial for restricting conformational freedom in the bond-forming step.
