近年来,对含有活性氢化合物的羧基化反应有不少报道,并有综述。其中所用的反应物,通常是含有强吸电子基团的化合物,所用的羧基化剂通常是活化了的二氧化碳衍生物,其中应用最广的是碱金属酚盐和二氧化碳作为羧基化剂,以它为羧化剂对脂肪族硝基化合物,氰基类化合物,酯类和酮类化合物能很方便地进行羧基化反应。文献报道 In recent years, there are many reports on the carboxylation reaction of active hydrogen compounds, and reviewed. The reactants used therein are usually compounds containing strongly electron-withdrawing groups. The carboxylating agents used are usually activated carbon dioxide derivatives, of which the most widely used are the alkali metal phenates and carbon dioxide as the carboxylating agent, with which Carboxylation of aliphatic nitro compounds, cyano compounds, esters and ketones can easily carry out the carboxylation reaction.
