摘要
本文在不同的pH和温度条件下测定了一批苯硫基,苯亚砜基和苯砜基乙酸酯的水解数据。获得了lgk对pH和温度的二元回归方程,发现了苯硫基乙酸酯水解中的邻基参与效应,并得出了邻基加速因子A与pH的关系。
Batch data for hydrolysis of phenylthio-, phenylsulf inyl and phenylsul-fonyl acetates have been determined at various pH values and temperatures. The dual regression equations of Igk vs pH and 1/T were obtained. Neighbouring group participation in the hydrolysis of phenylthio acetates was discovered, and the relationships between anchimeric assistance(A) and pH were established.
