Three new C-bonded cyclotriphosphazenes, [N3P3(2-thienyl)6], 2, [N3P3(3-thienyl)6], 4, and [N3P3(3,3′-bithienyl-2,2′-ylene)3], 6, have been prepared by two new synthetic procedures and are the first examples of non-spiro and trispirocyclotriphosphazene derivatives composed of thiophene and 3,3′-dithiophene substituents, respectively. Their 1H, 13C and 31P NMR parameters are given. The solid state structures of 2, 4 and 6 have been determined by X-ray crystallography.
三种新型C-键合的环三磷杂烯,[N3P3(2-噻吩)6],2,[N3P3(3-噻吩)6],4和[N3P3(3,3′-二噻吩-2,2′-亚基)3],6,通过两种新的合成方法制备而成,分别是由噻吩和3,3′-二噻吩取代基组成的非旋转和三旋转环三磷杂烯衍生物的首个实例。它们的1H、13C和31P NMR参数已给出。2、4和6的固态结构已通过X射线晶体学确定。
