An improved process for converting N-hydroxythioimidates to N-(methylcarbamoyloxy)-thioimidates by reaction with methylcarbamoyl chloride at pH above 10 in a two-phase reaction medium: water and a water-immiscible organic solvent.
一种改进的方法,通过在pH值高于10的两相反应介质中,将N-羟基硫代亚胺酯与甲基氨甲酰氯反应,转化为N-(甲基氨甲酰氧基)-硫代亚胺酯。这两相反应介质包括水和一种与水不相溶的有机溶剂。
