The reaction of [RuCp(IPri)(CH3CN)2]PF6 (IPri = 1,3-bis(2,6-diisopropylphenyl)imidazol-2-ylidene) with HCCR (R = COOMe, COOEt, COMe) yields the allyl carbene complexes [RuCp(=C(R)-eta3-CHC(R)CH-IPri)]PF6. This conversion involves selective head-to-tail coupling of two alkynes and an unusual migratory insertion of the N-heterocyclic carbene into the ruthenium-carbon double bond of a ruthenacyclopentatriene intermediate.
[RuCp(IPri)(CH3CN)2]PF6（IPri = 1,3 - 双（2,6 - 二异丙基苯基）咪唑 - 2 - 亚基）与HCCR（R = COOMe、COOEt、COMe）反应生成烯丙基卡宾配合物[RuCp(=C(R)-η3-CHC(R)CH-IPri)]PF6。这种转化涉及两个炔烃的选择性头对尾偶联以及氮杂环卡宾向钌环戊三烯中间体的钌 - 碳双键的异常迁移插入。
