The Ru[double bond, length as m-dash]P double bond in the 5-coordinate terminal phosphido complex [Ru(eta(5)-indenyl)(PR(2))(PPh(3))] undergoes regioselective [2+2] cycloaddition with simple and activated alkynes to give metallaphosphacyclobutene complexes. These unusual examples of alkyne insertion into a metal-heteroatom bond represent potentially important intermediates in stereoselective routes to new phosphine reagents and ligands.
5 配位末端膦配合物 [Ru(η(5)-茚基)(PR(2))(PPh(3))] 中的 Ru[双键,长破折号]P 双键与简单和活化的炔烃发生区域选择性 [2+2] 环加成反应,生成金属磷杂环丁烯配合物。这些炔烃插入金属-杂原子键的不寻常例子代表了对新膦试剂和配体的立体选择性途径中潜在重要的中间体。
