N-substituted monochlorosuccinimides e.g., N-phenylmonochlorosuccinimide, can be prepared in a high yield by reacting a maleamic acid, e.g., N-phenylmaleamic acid, with phosgene in the presence of a catalyst,e.g., dimethylformamide .
在催化剂(如二甲基甲酰胺)存在下,马来酰胺酸(如 N-苯基马来酰胺酸)与光气反应,可以高产率制备 N-取代的单氯丁二酰亚胺(如 N-苯基单氯丁二酰亚胺)。
