《Pd-Catalyzed Cross-Coupling of Sb-Aryl Stibines with Halogenomethyl Arenes to Give Unsymmetric Diarylmethanes》 was written by Zhang, Dejiang; Xu, Zhi; Tang, Ting; Le, Liyuan; Wang, Cairong; Kambe, Nobuaki; Qiu, Renhua. Recommanded Product: 622-95-7This research focused onunsym diarylmethane preparation; halogenomethyl arene aryl stibine cross coupling palladium catalyst. The article conveys some information:
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. The experimental part of the paper was very detailed, including the reaction process of 1-(Bromomethyl)-4-chlorobenzene(cas: 622-95-7Recommanded Product: 622-95-7)
1-(Bromomethyl)-4-chlorobenzene(cas: 622-95-7) undergoes carbonylation in the presence of dimer of chloro(1,5-cyclooctadiene)rhodium(I) to yield the corresponding phenylacetic acid.Recommanded Product: 622-95-7 It can be synthesized by reacting 4-chlorobenzyl alcohol with bromodimethylsulfonium bromide (BDMS) It can also be synthesized by refluxing a mixture of 4-chlorobenzaldehyde, chlorotrimethylsilane, 1,1,3,3-tetramethyldisiloxane and lithium bromide.
