important, alternative pathway to normal substitution only if a tertiary carbonium ion or a cyclic transition state, with the incipient positive charge located on a tertiary C atom, is involved in the reaction.
研究了α-重氮酮1a - 1d,2和3a,b,c的乙酰水解。从1a – 1d获得的结果表明,仅当涉及叔碳原子或环状过渡态且正电荷位于叔碳原子上的叔碳离子或环状过渡态参与其中时,苯氧基的迁移才是正常取代的重要替代途径。反应。
