(Cl—CH2CH2)2N—P(=X)Cl2, X = O, reacts with 1,2-dimethylhydrazine in the presence of triethylamine to give the dihydrazide. Hexahydropyridazine as “cyclic hydrazine” leads to a tetracyclic side product formed by HCl elimination from the reactive 2-chloroethyl groups and active β-NH protons of the hexahydropyridazinyl substituents. The corresponding thio-compound, X = S. yields the monosubstitution product (Cl—CH2CH2)2N—P(=S)(N(CH3)—N(CH3)H)Cl. O-Benzylhydroxyamine hydrochloride substitutes both Cl-atoms at P to ioni (Cl—CH2CH2)2N—P(=S)(NH—O—CH2—C6H5)2. The corresponding phenylesters C6H5O—P(=X)(NH—O–CH2—C6H5)2, X = O, S, are prepared in a similar reaction.
