Di-t-butyl ketone and 5,5,7,7-tetramethylunde-can-6-one have been found to isomerize slowly under strongly basic conditions (ButO––ButOH, 185 °C), constituting the first examples of skeletal rearrangement through β-enolizable (homoenolizable) methyl groups.
已发现二叔丁基酮和5,5,7,7-四甲基unde-can-6-one在强碱性条件下(Bu t O – –Bu t OH,185°C)缓慢异构化,是第一个通过β-烯醇化(可同烯醇化)的甲基进行骨架重排的例子。
