Bisdiazoniura Tetrafluoroborates as Arylating Agents in Anionarylation of Acrylamides and Methacrylamides

摘要

Bisdiazonium tetrafluoroborates derived from benzidine, 4,4'-diaminodiphenylmefhane, and 4,4'-diaminodiphenylsulfone have been used as arylating reagents in the reactions of chloro-, bromo-, and thiocyanatoarylation of acrylamides and methacrylamides. Anionarylation proceeds via two diazo groups to give 3,3'-[4,4'-biphenyl(methane, sulfone)]bis[2-chloro(bromo, thiocyanato)(2-methyl)propionamides].
