Reaction of chlorocyclothiaphosphazenes NPCl2(NSOX)2 (X = Cl, Ph) and (NPCl2)2NSOX (X = Cl, F, Ph) with KSO2F in bulk leads to fluorination at the phosphorus centers. The substitution reaction follows a geminal pattern. Reactions of trans-NPF2(NSOPh)2 with Grignard reagents RMgX (R = Me, 'Bu) show substitution of fluorine by alkyl groups to be a slow process. The more reactive PhMgBr gives an acceptable reaction rate and good yields. Organolithium reagents offer organo-substituted cyclothiaphosphazenes in low to moderate yields, depending on the reagent used. Crystals of cis-NPF2(NSOPh)2 are monoclinic, space group P21/n, with a = 13.665(7) A, b = 10.676(1) A, c = 9.897(3) A, β= 90.55(3)°, V = 1443.8(9) A3, and Z = 4. The final R and wR values are 0.034 and 0.043, respectively. The PN and SN bond lengths vary from 1.571(2) to 1.590(2) A.
