Kinetic and stereochemical evidence for nucleophilic assistance in the nucleophilic hydrolysis of chlorosilanes
Abstract
Kinetic studies of the hydrolysis of chlorosilanes shows nucleophilic assistance by hexamethyl-phosphoric triamide, dimethyl sulphoxide, or dimethyl-formamide in nucleophilic substitution; the reaction is controlled by the entropy of activation, and takes place with retention of configuration at silicon instead of inversion as previous observed with acyclic chlorosilanes.
