Methyltriphenylphosphonium tribromide 1 acts as an efficient mild dethioketalization reagent with high selectivity for 2-phenyl and 2-vinyl 1,3-dithiannes 2 versus 2-alkyl 1,3-dithiannes and without any secondary bromination reaction of the investigated substrates.The reaction was also succesful with trimethylphenylammonium tribromide.
