A novel arylation of sulfonamides with boronic acids to afford various diaryl sulfones via visible light-mediated N–S bond cleavage other than typical transition-metal-catalyzed C(O)–N bond activation is described. This methodology...

This work describes a base-mediated borylsilylation of benzylic ammonium salts to synthesize geminal silylboronates bearing benzylic proton under mild reaction conditions. Deaminative silylation of aryl ammonium salts was also achieved in the presence of LiO t Bu. This strategy which is featured with high efficiency, mild reaction conditions, and good functional group tolerance provides efficient routes for late-stage functionalization of amines.
