di-iodosilane react with NaCo(CO)4 in ether at low temperatures to give silyltetracarbonylcobalt, SiH3Co(CO)4, and silylenebis(tetracarbonylcobalt), SiH2[Co(CO)4]2, respectively. Physical properties of both compounds are reported, together with i.r., mass, and n.m.r. spectra of SiH3Co(CO)4. Pyrolysis of gaseous SiH3Co(CO)4 at 120° yields H2, CO, SiH4, and a dark-coloured inert solid; some HCo(CO)4 is also present
碘硅烷和二碘硅烷在低温下与NaCo(CO)4在乙醚中反应,分别得到甲硅烷基四羰基钴,SiH 3 Co(CO)4和亚甲撑双(四羰基钴),SiH 2 [Co(CO)4 ] 2。报告了这两种化合物的物理性质,以及SiH 3 Co(CO)4的ir,质量和nmr光谱。气态SiH 3 Co(CO)4在120°上热解产生H 2,CO,SiH 4和深色惰性固体。一些HCo(CO)4在早期也存在。推断出固体产物的化学计量学和可能的交联聚合物性质,并概述了其金属涂层性能。SiH 3 Co(CO)4中的Si-Co键被HX(X = F,Cl,O / 2)破坏,得到SiH 3 X和HCo(CO)4,也被HgX 2(X = Cl,I ),得到SiH 3 X和Hg [Co(CO)4 ] 2。SiH 2 [Co(CO)4 ] 2的行为类似。没有将CO插入Si-Co键中;PPh 3与SiH 3 Co(CO)4缓慢反应取代CO并可能产生反式-SiH
