competition between 1,2- vs. 1,3-elimination and nucleophilic substitution. Favorskii rearrangement was the preferred process, but in those cases where electronic or steric effects were present, nucleophilic substitution became dominant. No evidence of ketene formation was detected. The mechanism of formation of the various rearrangement products is discussed.
制备了三卤代甲基酮,并根据1,2-消除1,3-消除和亲核取代之间的竞争对它们在碱性条件下的反应性进行了研究。Favorskii重排是首选方法,但是在存在电子或空间效应的情况下,亲核取代作用占主导地位。没有检测到乙烯酮形成的证据。讨论了各种重排产物的形成机理。
