Several cyclic α,β-unsaturated ketoximes, or their tosylates were subjected to the Beckmann rearrangement. With all compounds except 8b, groups located anti to the leaving group migrated efficiently, irrespective as to whether the migrating group was alkyl or olefinic. The olefinic group in 8b, however, resisted the migration and this was interpreted in terms of the steric effect in the transition
几种环状α,β-不饱和酮肟或它们的甲苯磺酸酯进行了贝克曼重排。与除所有化合物8b中,基团位于防有效迁移的离去基团,而不管作为迁移组是否是烷基或烯属。然而,8b中的烯基抵抗迁移,这是根据过渡态的空间效应来解释的。
