Decarboxylative radical addition to vinylsulphones and vinylphosphonium bromide: Some further novel transformations of geminal (pyridine-2-thiyl) phenylsulphones

Irradiation of O-acyl derivatives 1 of N-hydroxy-2-thiopyridone with visible light in the presence of phenyl vinyl sulphone or vinyl triphenylphosphonium bromide leads to the corresponding adducts 8 and 9 which can undergo a wide variety of further transformations.

RADICAL ADDITION TO VINYL SULPHONES AND VINYL PHOSPHONIUM SALTS

Alkyl radicals, derived from decarboxylation of carboxylic acids, add readily to phenyl vinyl sulphone and vinyl phosphonium bromide.The adducts may be further converted into a variety of useful synthetic intermediates.
