Zhang, Dejiang published the artcilePd-Catalyzed Cross-Coupling of Sb-Aryl Stibines with Halogenomethyl Arenes to Give Unsymmetric Diarylmethanes, Application In Synthesis of 613-33-2, the publication is Organic Letters (2022), 24(17), 3155-3160, database is CAplus and MEDLINE.
Herein, a general method for the synthesis of unsym. diarylmethanes RCH2R1 (R = 4-cyanophenyl, 3-fluorophenyl, 2-chloro-4-fluorophenyl, etc.; R1 = Ph, 4-methoxyphenyl, 3-furanyl, etc.) from (hetero)aryl Me halides RCH2X (X = Br, Cl) and Sb-aryl stibines I was described. This protocol shows a broad substrate scope and a good functional group tolerance. Drug mols., including beclobrate and bifemelane, and drug derivatives, including celecoxib, ibuprofen, and probenecid, were efficiently synthesized on a gram scale.
Organic Letters published new progress about 613-33-2. 613-33-2 belongs to catalysis-chemistry, auxiliary class Benzene, name is 4,4′-Dimethyldiphenyl, and the molecular formula is C9H9F5Si, Application In Synthesis of 613-33-2.
