Abstract

Abstract: Methyttriphenylphosphonium tribromide 1 acts as an efficient mild dethioketalization reagent with high selectivity for 2-pher? yZ and a-vinyl 1, 3-dithiannes 2 versus 2-alkyd 1, 3-dithiannes and without any secondary bromination reaction of ale investigated substrates. The reaction was also successful with trimethylphenylammonium tribromide.
