Three new C-bonded cyclotriphosphazenes, [N3P 3(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.

Unsubstituted and trimethyl-4,8-diphosphathiophenetriptycenes (4 and 3d) were synthesized by reduction of the corresponding phosphine oxides (8a and 8b) with trichlorosilane which were prepared by the reaction of trilithium salts, derived from tri-3-thienylphosphine oxides (7a and 7b), with P(OPh)3. The reaction of 3d with W(CO)5(THF) gave a 1:2 complex 12 in high yield.
