Abstract

A mild method for the preparation of aryl and alkenylsulfones from the cross-coupling reaction of organoboronic acids and sodium sulfinate salts is described. Optimized conditions utilize a catalytic amount of copper (II) acetate monohydrate with 1, 10- phenanthroline as ligand in the presence of 4Å molecular sieves. A co-solvent mixture of dichloromethane/DMSO was used, with reactions occurring at 40° C under an atmosphere ...
