The base catalysed rearrangements of diallylammonium rations and allylpropynylammonium rations are described. In most cases, the major product arises by a symmetry-allowed [3,2] sigmatropic rearrangement of the intermediate ylide. The minor products can be regarded as being derived by homolysis of the ylide into a radical pair followed by recombination.
描述了碱催化的二烯丙基铵比和烯丙基丙烯酰铵比的重排。在大多数情况下,主要产物是由中间内环的对称允许的[3,2]σ重排产生的。次要产物可以认为是通过将叶立德均质化为自由基对,然后进行重组而得到的。
