Reactions of a boryl-substituted acyclic silylene with carbon dioxide and monoxide are reported. The former proceeds through oxygen atom abstraction, generating CO (with rearrangement of the putative silanone product through silyl-group transfer). The latter is characterized by reductive coupling of CO to give an ethynediolate fragment, which undergoes formal insertion into the Si-B bond. The net conversion of carbon dioxide with two equivalents of silylene offers a route for the three-electron reduction of CO to [C O ] .
报道了一种硼基取代的无环硅烯与二氧化碳和一氧化碳的反应。前者通过氧原子夺取反应进行，生成一氧化碳（假定的硅酮产物通过硅基转移发生重排）。后者的特征是一氧化碳发生还原偶联生成乙炔二醇片段，该片段会正式插入硅 - 硼键中。二氧化碳与两当量硅烯的净转化为将一氧化碳三电子还原为[C O ]提供了一条途径。
