Solvent isotope effects in the ethanolysis of stericallyhindered arenesulfonyl chlorides ruled out a proton transfer in the rate‐determining step and agreed with a SN2 mechanism involving at least a second solvent molecule in the transition state (TS). The lack of a secondary kinetic isotope effect in the o‐alkyl groups allows us to disregard the possible contribution of σ–π hyperconjugation. The
在空间受阻的芳烃磺酰氯的乙醇化反应中,溶剂同位素的作用排除了速率确定步骤中的质子转移,并同意了S N 2机理,该机理涉及至少第二个处于过渡态(TS)的溶剂分子。邻烷基中缺乏次级动力学同位素效应,使我们可以忽略σ-π超共轭的可能贡献。测得的活化参数与涉及溶剂分子参与TS的S N 2机制一致,可能通过溶剂分子链形成环状TS。
