Abstract

Use of a silyl supported stannylene ( ^MesTerSn(Si ^tBu ₃) [ ^MesTer=2,6-(2,4,6-Me ₃C ₆H ₂) ₂C ₆H ₃] 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.
