Efficient synthesis of unsymmetrical S-(bromodifluoromethyl)diarylsulfonium salts for electrophilic bromodifluoromethylating reagents†
Abstract
A series of unsymmetrical S-(bromodifluoromethyl)diarylsulfonium salts 1 were readily synthesized by treatment of corresponding (bromodifluoromethyl)arylsulfoxides 2 and substituted
