Abstract

Described is the synthesis of novel arylated and alkynylated 2,4′-diphenyl sulfones based on what are, to the best of our knowledge, the first palladium(0)-catalyzed cross-coupling reactions of bis(triflates) of 2,4′-bis(hydroxy)diphenyl sulfone. The reactions proceed with very good site-selectivity.
