monoxide in order to elucidate the factors involved in silyl migration to coordinated CO. The tendency of M-Si bonds in d/sup 0/ complexes to insert unsaturated substrates was expected to be greater than in previously studied complexes, since bond strengthening by metal-to-silicon ..pi..-donation cannot occur. Crystal structures of two zirconium silyl compounds indeed reveal rather long Zr-Si bonds. They
他们关于早期过渡金属-甲硅烷基反应性的研究包括与一氧化碳的反应,以阐明甲硅烷基迁移到配位 CO 中涉及的因素。d/sup 0/ 配合物中的 M-Si 键插入不饱和底物的趋势是预计比以前研究的复合物更大,因为金属对硅的键合增强..pi..-donation 不会发生。两种锆甲硅烷基化合物的晶体结构确实揭示了相当长的 Zr-Si 键。他们在此报告了 -Si(SiMe/sub 3/)/sub 3/ 的锆和铪衍生物的制备以及这些和其他早期过渡金属甲硅烷基与 CO 的反应。
