A noteworthy feature of the reaction system is its high tolerance of functional groups due to the moderate nucleophilicity of organozinc reagents and the mild reaction conditions. Moreover, spectroscopic and crystallographic analyses of the zinc complex of the double Reformatsky product support the proposed mechanism of reaction site discrimination for ketones, aldehydes, nitriles, carboxylic acid anhydrides
已经开发了双重Reformatsky反应,将两个链烷酸锌分子串联添加到羰基化合物中以及将其合成应用到一系列δ-羟基-β-酮酸酯中。加速双重Reformatsky反应的关键被认为是原位生成的烷氧基锌与底物或二齿胺的吡啶基配位的复合物诱导的邻近效应。由于有机锌试剂的中等亲核性和温和的反应条件,该反应系统的显着特征是其对官能团的高度耐受性。此外,双Reformatsky产品的锌配合物的光谱和晶体学分析支持所提出的酮,醛,腈,羧酸酐和酯的反应位点鉴别机制。
