The role of conformational flexibility in the hypervalency of organosilanes
Abstract
Organosilanes with the potentially coordinating group -N[(CH ) NMe ] or -N(CH CH OMe) have been prepared and characterized by proton, carbon, and silicon NMR spectroscopy. None of the compounds showed evidence of hypervalency, suggesting that the conformationally-flexible bridging framework produces an unfavorable entropy of coordination. 2 3 2 2 2 2 2
