在无金属催化条件下,多种醛或羧酸与季铵盐选择性地发生酯化反应合成酯.提出了可能反应机理包括醛转化为羧酸的自由基机理过程及季铵盐的C-N键断裂生成碘代烃的过程.

关键词: 季铵盐, 酯化反应,

A metal-free esterification of various aldehydes or carboxylic acids with quaternary ammonium salts has been developed for selective synthesis of esters. A possible mechanism containing radical process that aldehyde converts to carboxylic acid and the generation of iodohydrocarbon via C-N bond cleavage of quaternary ammonium salt is proposed.

Key words: quaternary ammonium salt, esterification, aldehyde
