N－取代三氯乙酰胺合成N，N″－多亚甲基双［N′－（4－氯苯基）］脲

Synthesis of N,N″ polymethylenebis(N′ 4 chlorophenyl)ureas from N Substituted Trichloroacetamide

通过Ｎ－取代三氯乙酰胺与不同的脂肪二胺反应，合成了５种新的Ｎ，Ｎ″－多亚甲基双［Ｎ′－（４－氯苯基）］脲［ＡｒＮＨＣＯＮＨ（ＣＨ２）ｎＮＨＣＯＮＨＡｒ，ｎ＝２～６，Ａｒ＝４－ＣｌＣ６Ｈ４］，其结构经元素分析。

Five new N,N″ Polymethylenebis(N′ 4 chlorophenyl)ureas [ArNHCONH(CH 2) n NHCONHAr,n=2￣6,Ar=4 ClC 6H 4], were prepared by the reaction of N substituted trichloroacetamide with various diamines. Their structures were confirmed by elemental analysis, 1H NMR and IR.
