A novel palladium(0)-catalyzed addition of diphenyl disulfide to allenes leading to vicinal disulfides and its application to carbonylation with carbon monoxide

Tetrakis(triphenylphosphine)palladium(0) catalyzes a highly regioselective bisthiolation of terminal allenes with diphenyl disulfide to afford the corresponding 2-(phenylthio)-substituted allyl sulfides in good yields. In addition, this reaction system can be applied to the carbonylation under pressurized carbon monoxide.
