3-Azido-5,6-diphenyl-1,2,4-triazine (1) and 3-azidophenanthro[9,10-e]-1,2,4-triazine (2) are synthesized in high yield (-75%), 1 and 2 react with triphenylphosphine to afford phosphazenes 5 and 6 with a covalent structure. Reactions of 1 and 2 with trialkyl phosphites 3b,c produce phosphazenes 7a,b and 8a,b which have the phosphonium dipolar ion structure, 1 reacts with diethyl phosphonate (4a) to give the phosphoramidate 10a, dissociating to the corresponding amine 11 on reaction with dimethyl phosphonate. Possible reaction mechanisms are proposed for the formation of the new adducts.
