N-nucleophiles in basic aqueous media produced the corresponding substitution products in the absence of a transition-metal catalyst. Mechanistic studies, using (S)-1 and p-MeC6H4CH(OAc)CHCHPh as substrates, led to propose a BAL1 cleavage of the ester function leading to a stabilized allylic carbocation as intermediate.
在碱性水介质中用C-,O-,S-和N-亲核试剂处理1-乙酰氧基-1,3-二苯基丙烯(1)可以在没有过渡金属催化剂的情况下产生相应的取代产物。使用(S)-1和p -MeC 6 H 4 CH(OAc)CH = CHPh作为底物的机理研究提出了酯功能的BAL 1裂解,导致稳定的烯丙基碳正离子化为中间体。
