摘要：

The complexes [RuCp(PR3))(CH3CN)2]PF6 (R = Me, Ph, Cy) react with 1,6-heptadiyne and HC=CR' (R' = Ph, C6H9, n-Bu, H), most likely via a ruthenacyclopentatriene intermediate, to give the ruthenium allyl carbene complexes [CpRu(=CH-eta(3)-C(CH2)(3)CCHPR3)]PF6 and [CpRu(=C(R')-eta(3)-CHC(R')CHPMe3)/PF6, respectively. In the case of R = Cy, the allyl carbene complex rearranges to afford the complex [CpRu(eta(3)-CH2C(CH2)(3)-CCH2PCy2(eta(2)-C6H9)PF6, featuring an eta(2)-coordinated cyclohexenyl ligand. This reaction involves dehydrogenation of one cyclohexyl substituent of the phosphine ligand.
