conditions for the thermal isomerization of cyclobutanols depend on the relative configuration of halohydrins. Based on the experiments performed, we assume that the halocyclobutanols undergo ring contraction to form cyclopropyl ketones, which are isomerized by means of hydrogen halide.
我们开发了一种通过卤代
环丁醇热开裂制备芳基烷基酮和α,β-不饱和酮的新方法。
环丁醇热异构化的反应条件取决于卤代醇的相对构型。基于所进行的实验,我们假设卤代
环丁醇发生缩环形成环丙基酮,后者通过卤化氢异构化。
