Allylic nitro compounds 1a–d undergo [2,3]-sigmatropic rearrangement in refluxing 1,2,4-trichlorobenzene, to afford rearranged alcohols 3a–d and carbonyl compounds 4a–d; the heating, under the same conditions, of a mixture of nitroalkenes 7a–c, propargyl alcohols or amine 8 and ButOK promotes a one-pot formation of allylic alcohols 3a–c.
烯丙基硝基化合物1a–d在回流的1,2,4-三氯苯中经历[2,3]-σ-迁移重排,生成重排后的醇3a–d和羰基化合物4a–d;在相同条件下,加热硝基烯烃的混合物7a–c、丙炔醇或胺8和ButOK能够促进一锅生成烯丙基醇3a–c。
