报道烯(炔)基硫醚与α-重氮羰基化合物, 在[RuCl2(p-cymene)]2催化下, 经由金属卡宾发生硫叶立德[2,3]-σ重排反应(Doyle-Kirmse反应). 在Ru(II)作用下, α-重氮羰基化合物与烯丙基硫醚的反应以较好收率生成相应的[2,3]-σ重排产物高烯丙基硫醚. 同样条件下与炔丙基硫醚的反应则生成[2,3]-σ重排产物联烯和呋喃衍生物, 后者是联烯进一步在Ru(II)作用下重排的产物.

The Doyle-Kirmse reaction, namely the [2,3]-sigmatropic rearrangement of sulfonium ylides generated from α-diazo carbonyl compounds and sulfides has been for the first time catalyzed by [RuCl2- (p-cymene)]2. The reaction with allyl sulfides afforded the corresponding [2,3]-sigmatropic rearrangement products in moderate to good yields. The reaction with propargyl sulfide gave a mixture of allenic sulfide and furan. The former is the [2,3]-sigmatropic rearrangement product, while the latter is derived from the further rearrangement of the allene product under Ru(II) catalysis.

Key words: ruthenium(II) catalyst, α-diazo carbonyl compound, [2,3]-sigmatropic rearrangement of sulfonium ylide
