Hydrogen bonding nucleophilicity enhanced

An uncharged nucleophile may also play the role of a Bronsted base if interaction with a protic substrate can increase its nucleophilicity [Eqs. (41) and (42)]. This pathway, formulated by Allen and Modena (137), seems to be important in many solvolytic reactions (7). There is evidence that more than one solvent molecule participates in the solvolysis of chlorosilanes (7,137,244). One functions as the nucleophile attacking silicon, while the others, forming hydrogen bonding complexes, enhance the nucleophilic reactivity. [Pg.297]
