The reactions of N-dichlorophosphoryl-P-trichlorophosphazene, Cl3P=N-P(O)Cl-2, with 1-methylpiperazine, 1-benzylpiperazine, 4-methylpiperidine, 2-methylpiperidine, 4-hydroxybenzaldehyde, and hydroxylaminehydrochloride were studied. Experimental studies were carried out in argon atmosphere. Pentaaminophosphazenes were obtained from 1-methylpiperazine and 1-benzylpiperazine. Phosphinoyl compounds formed from 4-methylpiperidine and 2-methylpiperidine. Phosphoryl compound was obtained from 4-hydroxybenzaldehyde. Oxime derivative of tris(4-formylphenoxy) phosphoryl was prepared from hydroxylamine hydrochloride.
