Re(I)-Catalyzed Hydropropargylation of Silyl Enol Ethers Utilizing Dynamic Interconversion of Vinylidene–Alkenylmetal Intermediates via 1,5-Hydride Transfer

Re­(I)-catalyzed hydropropargylation
reaction of silyl enol ethers
was realized utilizing dynamic interconversion of vinylidene–alkenylmetal
intermediates, where alkenylmetals underwent 1,5-hydride transfer
of the α-hydrogen to generate vinylidene intermediates. Furthermore,
this process was found to be in an equilibrium.

通过动态转化乙烯基乙烯基-金属中间体，实现了硅基烯醇醚的催化加成丙炔反应，其中烯基金属经历了α-氢的1,5-氢转移以生成乙烯基中间体。此外，这一过程被发现处于平衡状态。
