The invention provides a process for synthesizing chlorinated pyrimidines. The process includes reacting imidoyl chloride compounds with phosgene (COCl
2
). The imidoyl chloride compounds can be supplied as starting materials or can be produced by reacting organic amides with phosgene or reacting organic nitrites with hydrogen chloride. Phosgene may be replaced by equivalent reagents. The chlorinated pyrimidines, such as 4,6-dichloropyrimidine, can be used to synthesize other compounds useful in a variety of compositions, such as fungicides, pesticides, and pharmaceuticals.
该发明提供了一种合成氯代嘧啶的方法。该方法包括将亚胺酰氯化合物与光气(COCl2)反应。亚胺酰氯化合物可以作为起始材料供应,也可以通过将有机酰胺与光气反应或将有机亚硝酸盐与氯化氢反应来制备。光气可以被等效试剂替代。氯代嘧啶,如4,6-二氯嘧啶,可用于合成其他在各种组合物中有用的化合物,如杀菌剂、农药和药品。
