Magnesium methoxide (Mg(OCH3)2) and calcium chloride have been shown to facilitate the direct aminolysis of esters by ammonia to primary amides. Methyl, ethyl, isopropyl, and tert-butyl esters were converted to the corresponding carboxamides in good yields. Reactions have been run on a larger scale and without the safety liability inherent in the use of magnesium nitride (Mg3N2). Ammonium chloride
甲醇镁(Mg(OCH 3)2)和氯化钙已被证明可以促进氨将酯直接氨解为伯酰胺。将甲基,乙基,异丙基和叔丁基酯以良好的产率转化为相应的羧酰胺。反应已进行了较大规模,并且没有使用氮化镁(Mg 3 N 2)时固有的安全隐患。氯化铵和胺盐酸盐已成功用于代替甲醇与甲醇镁。
