Use of a silyl supported stannylene ( TerSn(Si Bu ) [ Ter=2,6-(2,4,6-Me C H ) C H ] enables activation of white phosphorus under mild conditions, which is reversible under UV light. The reaction of a silylene chloride with the activated P complex results in facile P-atom transfer. The computational analysis rationalizes the electronic features and high reactivity of the heteroleptic silyl-substituted stannylene in contrast to the previously reported bis(aryl)stannylene.
使用硅基支持的亚锡烯（TerSn(SiBu) [Ter = 2,6-(2,4,6-MeC6H2)2C6H3]）能够在温和条件下活化白磷，且在紫外光下该过程是可逆的。二氯硅烯与活化的磷配合物反应可实现轻松的磷原子转移。与先前报道的双（芳基）亚锡烯相比，计算分析阐明了这种杂配硅基取代亚锡烯的电子特性和高反应活性。
