N′-diphenylthiourea, triethylamine, and primary alkyl halides is described. Microwave-assisted heating and a catalytic amount of 4-(dimethylamino)pyridine (DMAP) further improved the yields. Both aromatic and aliphatic carboxylic acids were converted to the corresponding thioesters, and many functional groups were compatible with this reaction. Several possible reaction intermediates were investigated, and the
描述了直接从羧酸,N,N'-二苯基硫脲,三乙胺和伯烷基卤化物一锅法合成硫酯的方法。微波辅助加热和催化量的4-(二甲基氨基)吡啶(DMAP)进一步提高了收率。芳族和脂族羧酸均被转化为相应的硫酯,并且许多官能团与该反应相容。研究了几种可能的反应中间体,衍生自烷基卤化物和叔胺的季铵盐是生产硫酯的中间体。提出了这种硫酯化反应的新反应机理。
