Abstract

From the reactions of the geminal tetrachloro-1′.3′-propanedioxycyclotriphosphazatriene, N₃P₃CI₄-[O(CH₂)₃O]. with primary and secondary amines. the following derivatives have been isolated: N₃P₃Cl₃R[O(CH₂)₃O]. R = NHC₃H₅. NC₄H₈. NC₄H₈O. NC₅H₁₀; N₃P₃Cl₂R₂(O(CH₂)₃O]. R = NHEt. NHC₃H₅. NHC₆H₁₁. NMe₂. NC₄H₈ (3 isomers). NC₄H₈O, NC₅H₁₀; N₃P₃R₄[O(CH₂)₃O], R = NHEt. NHC₃H₅, NMe₃. NC₄H₈, NC₄H₈O. Their ¹H, ¹³C and ³¹P n.m.r. spectra are reported. The non-equivalence of the OCH₂ and/or the CCH₂ protons of the 1′.3′-propanedioxy group is used to distinguish between geminal and nongeminal cis- and trans-isomers in N₃P₃Cl₂R₂[O(CH₂)₃O]. Primary amines give geminal bis-derivatives. secondary amines mainly nongeminal trans-isomers in N₃ P₃Cl₂R₂[O(CH₂)₃O], but for pyrrolidine cis- and geminal isomers were also isolated.
