Crystal structures of a new thiazepine and diazepine (seven‐membered rings) have also been determined and compared with thiazine (six‐membered ring). In this method, N‐methylimidazolium nitrate [Hmim][NO3] has been used as a catalyst that acts as an environmental friendly system.
本文介绍了1,5-苯并噻氮杂类和1,5-苯并二氮杂类衍生物的合成方法和反应机理。在这项研究中,已经用新方法制备了36种噻嗪类和二氮杂品(大多数是新的),并通过分光镜方法对其结构进行了表征。还确定了新的噻氮平和二氮杂(七元环)的晶体结构,并将其与噻嗪(六元环)进行了比较。在此方法中,硝酸N甲基咪唑鎓盐[ Hmim ] [NO 3 ]被用作催化剂,对环境无害。
