Ru(ii)-catalyzed rearrangement of the allenic sulfide bearing propargyl moiety: efficient formation of benzene derivatives†‡
Abstract
[RuCl2(p-cymene)]2 efficiently catalyzes the rearrangement of allenic sulfides bearing the propargyl moiety to afford 1,2,4-trisubstituted benzene derivatives. The alkyne-Ru(II) carbene [2 + 2] cycloaddition/ring opening process has been proposed in the reaction mechanism.
