- 論文の詳細を見る
The acyloxy exchange reactions of acyloxysilane with carboxylic acids have been studied kinetically. The rate of reaction has been found to proceed faster with a stronger attacking acid and more basic leaving acyloxy group. The rate was markedly accelerated by the addition of base. The steric effect due to substituents on the silicon atom and hydrogen-deuterium kinetic isotope effects have been examined. A mechanism involving the 5-coordination of the silicon atom prior to the rate-determining proton transfer has been suggested.
