In the reaction of 2-chloro-1,5-dimethyl-3-phenyl-1,3,5-triaza-2λ 3 -phosphorinane-4,6- dione (1) and 2-chloro-1,3,5-triphenyl-1,3,5-triaza-2λ 3 -phosphorinane-4,6-dione (2) with (2-chloroethyl)amine hydrochloride or bis(2-chloroethyl)amine hydrochloride in the presence of triethylamine the corresponding (2-chloroethyl)amino- and bis(2-chloroethyl)amino-substituted 2λ 3 -phosphorinane-4,6-diones (3-6) are formed. Oxidation with the hydrogen peroxide- urea-1: 1-adduct gives the corresponding 2-oxo-2λ 4 -phosphorinane-4,6-diones (7-10), in the same manner as described in the literature for the 1,3,5-trimethyl-1,3,5-triaza-2λ 4 -phosphorinane- 4,6-diones [6]. Hydrolysis of 1 leads to 2-hydro-1,5-dimethyl-3-phenyl-1,3,5-triaza- 2λ 4 -phosphorinane-4,6-dione (11). Compounds 3 -11 have been characterized via their  1 H,  13 C and  31 P NMR spectra, mass spectra, and, with the exception of 9, through elemental analyses.
