The 1,4-additon of Grignard reagents to ß-nitrostyrene to give 1,1-diaryl-2-nitroethanes and their subsequent conversion via a modified Nef reaction into 1,1-diaryl-2,2-dimethoxyethanes (diarylacetaldehyde dimethyl acetals) is described. The scope of the reaction has been briefly explored and one example demonstrated on a large scale.
介绍了格氏试剂与 ß-硝基苯乙烯的 1,4-加成反应,从而得到 1,1-二芳基-2-硝基乙烷,随后通过改进的奈夫反应将其转化为 1,1-二芳基-2,2-二甲氧基乙烷(二芳基乙醛二甲基缩醛)。 简要探讨了该反应的范围,并以一个实例进行了大规模演示。
