水的参与对不同路易斯酸碱对络合作用的影响
Interaction of Water to the Complexation of Lewis Acids and Bases
摘要
Abstract
This work systematically investigates the coordination and interconversion behaviors of tris(pentafluoro-phenyl)borane(BCF)with eleven substituted amines in the presence of varying amounts of water,employing 11B/19F-NMR spectroscopy and theoretical calculations.The catalytic activity of these systems in reactions with phenylsilane was further explored.The results indicate that the amine/BCF/H2O systems primarily exist in three coordination modes:B—N coordination,boronium hydroxide(B—OH)species,and a three-component hydrogen-bonded complex of the type"LB···H—(H)O···LA".When the molar ratio of H2O reaches or exceeds that of BCF,the coordi-nation equilibrium shifts significantly toward the hydrated three-component form.This shift markedly alters the protonation capability of the substrates and their reactivity in silane reduction,thereby determining the activation pathway with PhSiH3.This study not only provides experimental evidence to elucidate the reaction mechanisms of boranes under aqueous conditions but also offers theoretical and practical guidance for designing and expanding Frustrated Lewis Pairs(FLPs)catalytic systems in aqueous environments.关键词
