α-bromoalkyl acrylates (aliphatic and alicyclic) results in high yields when carried out on 30 mesh activated granular zinc, between 14 and 20°C in ethereal solvents (THF, DME, ether). Under these conditions duplication can be minimized (5–15%) especially with t-butyl acrylates. These α-functional allylic organozinc derivatives have been characterized by hydrolysis and coupling with benzaldehyde.
各种α-溴烷基丙烯酸酯(脂族和脂环族)的溴锌衍生物的制备,在醚化溶剂(THF,DME,乙醚)中,在14至20°C的30目活化的粒状锌上进行时,可产生高收率。在这些条件下,尤其是使用丙烯酸叔丁酯时,重复现象可以降到最低(5-15%)。这些α-官能烯丙基有机锌衍生物的特征在于水解并与苯甲醛偶联。
