Synthesis and structural studies (1H, 13C, 31P NMR and X-ray) of new C-bonded cyclotriphosphazenes with heterocyclic substituents from novel phosphinic acid derivatives

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 thioph...

Summary: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 H-1, C-13 and P-31 NMR parameters are given. The solid state structures of 2, 4 and 6 have been determined by X-ray crystallography.
