摘要：

Use of a silyl supported stannylene ((Mes)TerSn((SiBu3)-Bu-t) [(Mes)Ter=2,6-(2,4,6-Me3C6H2)(2)C6H3] enables activation of white phosphorus under mild conditions, which is reversible under UV light. The reaction of a silylene chloride with the activated P-4 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.
