Electroreductive acylation of 3-aryl substituted α,β-unsaturated esters and nitriles in the presence of aliphatic carboxylic anhydrides using areactive metal anode (Mg, Al, Zn) in an undivided cell afforded the corresponding β-acyl compounds in moderate to good yields. It was found that anionic species formed by electron transfer from a cathode may be stabilized by metal ions freshly formed from an
在芳族羧酸酐存在下,使用芳族活性金属阳极(Mg,Al,Zn)在未分隔的电池中,对3-芳基取代的α,β-不饱和酯和腈进行电还原酰化反应,可以以中等至良好的收率得到相应的β-酰基化合物。已发现,与以前报道的使用α-烯烃的方法相比,通过从阳极新鲜形成的金属离子可以稳定由阴极电子转移形成的阴离子物质,并使之经受羧酸酐的亲电攻击,从而以高收率获得β-酰基产物。分裂的细胞。
