from benzidine, 4,4′-diaminodiphenylmethane, 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].
