o-nitrobenzylketones are prepared by reacting a trans-.beta.-substituted amino-2-nitrostyrene with a lower alkanoyl halide, halo-lower alkanoyl halide, phthalimido-lower alkanoyl halide, benzoyl halide or substituted benzoyl halide, and subsequently hydrolyzing the resulting product to yield the desired o-nitrobenzylketone.
通过将反式-β-取代氨基-2-硝基苯乙烯与较低的酰卤、卤代较低酰卤、邻苯二甲酰亚胺较低酰卤、苯甲酰卤或取代苯甲酰卤反应,然后水解得到所需的邻硝基苄酮。
