Twelve　polyhedronylcarbonyl　chloroethylureas　were　synthesized　by　the　condensation　of　acylfluoride　and　chloroethylurea　in　the　ionic　liquid　[bmim][BF4]　with　the　polyhedron　dicarboxylic　acids　as　starting　materials.　The　structures　have　been　characterized　by　H-1　NMR,　C-13　NMR　and　MS　techniques.　Comparison　with　the　traditional　methods　of　acylchloride　as　intermediate,　this　procedure　has　the　advantages　of　better　yield,　simplified　operation　and　environmental　benignity.
