In dimethylsulfoxide solution in the presence of excess of powdered sodium hydroxide, N-subsituted trichloroacetamides 1 are used as in situ isocyanate generating reagents which can react with carboxamides or sulfonamides 2 to afford acylureas or sulfonylureas 3.
在过量粉末状氢氧化钠存在的二甲基亚砜溶液中,N-取代的三氯乙酰胺1被用作原位异氰酸酯生成试剂,能够与羧酰胺或磺酰胺2反应,生成酰基脲或磺酰脲3。
