Abstract
A stable dialkylstannylene [2,2,5,5-tetrakis(trimethylsilyl)stannacyclopent
ane-1,1-diyl] was synthesized by the reduction of the corresponding dichlor
ostannane with KC, in THF at low temperature. The stannylene showed reversi
ble complexation with tetrahydrofuran (THF) with DeltaH = - 7.0 kcal mol(-1
) and DeltaS = - 48 cal mol(-1) K-1, suggesting that the complexation is en
ergetically favored but disfavored by the steric hindrance. No such complex
ation with THF was observed for the corresponding germylene and silylene. (
