Enolates of carbonyl compounds having a methine α-carbon undergo 2-nitro-1-alkenylation (nitroolefination) to form quarternary C-atom next to the carbonyl group on reaction with β-nitroenamines via an addition elimination process. The geometry of the resulting nitroolefins proved to be of the E type.
具有甲亚甲基α碳的羰基化合物的烯醇盐在与β-
硝基胺反应时,通过加成消除过程发生2-硝基-1-烯烃化(硝基烯烃化),形成与羰基团相邻的四级碳原子。得到的硝基烯烃的几何构型被证明为E型。
