由氰酸铅与酰氯在二氧六环中制备酰基异氰酸酯,产物与苯胺作用除得酰基脲外,还得到一个副产物,本文测定其结构为RCONHCONHCONHC_6H_5(其中R为烷基)。

The acyl isocyanate was prepared from lead cyanate and acid chloride in dioxane. The product was treated with aniline to give acylurea. A by-product was also obtained. The structure of the product was determined as RCONHCONHCONHC_6H_5 (where R is alkyl).
