Bisdiazonium tetrafluoroborates as arylating agents in anionarylation of acrylamides and methacrylamides

Anionarylation of acrylic and methacrylic acids derivatives with p- and m-phenylenebisdiazonium tetrafluoroborates

“…Chloro-, bromo-and thiocyanatoarylation of amides of acrylic and methacrylic acids with bisdiazonium tetrafluoroborates derived from benzidine, diaminodiphenylmethane, or diaminodiphenylsulfone involved the both diazo groups due to their spatial accessibility [6].…”

Synthesis and Antimicrobial Activity of Products Obtained via Anionarylation of Acrylic and Metahcrylic Acids Amides and Nitriles by 5-Carboxyphenylene-1,3-Bisdiazonium Salts

“…Thus, we obtained the products of halogen-and thiocyanatoarylation of acrylic and methacrylic acids amides via interaction between aryldiazonium tetrafluoroborates based on benzidine, diaminodiphenylmethane and diaminodiphenylsulfone with the participation of both diazogroups [6]. m-Phenylenebisdiazonium chlorides form monochlorarylation adducts in the presence of acrylonitrile, acrylates and methacrylates due to electronic and steric effects [7].…”
