developed for effective Friedel–Craft’s acylation of aromatic compounds. Acylation of aromatic compounds with acetamide/SO2Cl2 was much more effective and faster than analogous (acetamide/SOCl2) and (acetamide/POCl3) reagents even under conventional conditions. However, microwave and ultrasonic assisted reactions afforded high yields of products in very short reaction times (30–40 min under sonication and 3–4 min
已开发出乙酰胺/ SO 2 Cl 2试剂,用于有效地进行Friedel-Craft芳族化合物的酰化反应。即使在常规条件下,与类似的(乙酰胺/ SOCl 2)和(乙酰胺/ POCl 3)试剂相比,用乙酰胺/ SO 2 Cl 2酰化芳族化合物也更有效和更快。但是,微波和超声辅助反应可在非常短的反应时间内(在超声处理下30–40分钟,在微波辅助条件下3-4分钟)提供高产率的产品。
