  Nonmetathetic Activity of Ruthenium Alkylidene Complexes: 1,4-Hydrovinylative Cyclization of Multiynes with Ethylene

  摘要：

  An efficient 1,4-hydrovinylative cyclization reaction of triynes and tetraynes catalyzed by ruthenium alkylidene complexes under ethylene is described. The regioselectivity of vinyl group incorporation can be controlled by the nature of the substituent on the alkyne, and the Grubbs second-generation catalyst is the most effective among typical ruthenium alkylidene complexes.
