一种α,β不饱和羧酸亚胺酯的合成、表征与晶体结构

Synthetic characterization and crystal structure of a ketenimine rearrangement products

报道了一种烯酮亚胺反应活性中间体的重排产物——α,β不饱和羧酸亚胺酯化合物的合成,并通过核磁共振氢谱和X射线单晶衍射对其结构进行了表征.单晶X-衍射分析表明:该化合物三斜晶系,P-1空间群,晶胞参数a=7.9832(2)A,b=8.3409(2)A,c=14.5288(4)A,α=81.1650(10)°,β=74.4740(10)°,γ=63.9960(10)°,V=837.03(4)A^3.实验结果为烯酮亚胺的重排反应这一化学理论提供了有力的证据.

The synthesis of anα,β-unsaturated carboximidate via a rearrangement reaction of ketenimine was reported.The compound was characterized by^1H NMR and single crystal X-ray diffraction.X-ray diffraction analysis of single crystal shows that the compound belongs to the triclinic crystal system and is crystallized in space group P-1,cell parameters:a=7.9832(2)A,b=8.3409(2)A,c=14.5288(4)A,α=81.1650(10)°,β=74.4740(10)°,γ=63.9960(10)°,V=837.03(4)A^3.It provides strong evidence for the chemical theory of rearrangement chemistry of ketenimine.
