A facile "one-pot" synthesis of thiophosphoryl xanthates was carried out by using a mild base 1,8-diaza[5,4,0]bicyclo undec 7-ene (DBU)-catalyzed sequential reaction of excess alcohols with carbon disulfide and diethoxy thiophosphoryl chloride. The overall yields are excellent (65-88%).
通过温和碱 1,8-二氮杂[5,4,0]双环十一碳 7-烯(DBU)催化的过量醇与二硫化碳和二乙氧基硫代磷酰氯的顺序反应,实现了硫代磷酰黄原酸盐的简便 "一锅式 "合成。总体收率极高(65-88%)。
