N-Alkyldiphenylsulfilimines, Ph2S+N−R, were prepared by treating diphenylsulfilimine with alkyl halides in refluxing chloroform. Reactions of N-benzyldiphenylsulfilimine with activated olefins and acetylenes were investigated and found to give products consistent with nuclephilic attack of −NCH2Ph followed by SN bond cleavage with or without hydrogen transfer. In general, the reaction conditions had

In this study, we report a highly selective coupling reaction between triarylbismuthines and isocyanides using palladium diacetate as the catalyst, affording alpha-diimines, with the formation of three C-C bonds. Among several aryl sources,(Ar-YLn : Y = B, Sn, Pb, Sb, Bi, I), only triarylbismuthines successfully undergo coupling with isocyanides to selectively afford alpha-diimines. The coupling reaction exhibits the advantages of high atom economy and convenient operation, with no need for any additive.
