Abstract Solvent-free acetylation of alcohols, phenols, amines, and thiols with acetic anhydride (Ac2O) in the presence of 0.1 mol% (13 mg) anhydrous NiCl2, an inexpensive and easily available catalyst, is described. Excellent yields, short reaction time, and mild reaction conditions are important features of this method.
摘要描述了在 0.1 mol% (13 mg) 无水 NiCl2(一种廉价且易于获得的催化剂)存在下,用乙酸酐 (Ac2O) 对醇、酚、胺和硫醇进行无溶剂乙酰化。收率高、反应时间短、反应条件温和是该方法的重要特点。
