摘要：

A procedure for generating the ruthenium hydride complex Ru(H)(H-2)Cl(PCy3)(2) in 95% yield is presented. Following a novel insertion-elimination pathway, this hydride can. react with propargyl or vinyl halides to make metathesis-active vinyl and alkyl carbene species with the general formulas (PCy3)(2)Cl2Ru=CH-CH=CR2 and (PCy3)(2)Cl2Ru=CHR, respectively. Tertiary propargyl chlorides work best, giving Ru-vinyl carbenes in extremely high yield.
