“…The reactions of trimeric phosphazene (N 3 P 3 Cl 6 ) with primary and secondary amines, diamines, polyamines 1-4 and aryloxides [5][6][7][8][9][10][11][12][13][14] under different conditions have been studied. The phenoxy derivatives of trimeric phosphazene (N 3 P 3 Cl 6 ) and tetrameric phosphazene (N 4 P 4 Cl 8 ) were used in the synthesis of new, small-molecule organocyclophosphazenes.…”

Synthesis and spectroscopic properties of geminal-bis(tert-butylamino)cyclotriphosphazenes obtained by the reaction of spiro and ansa phenoxycyclotriphosphazenes with the tert-butylamine and the crystal structure of 4,4'-bis(tert-butylamino)-2,6',6',10--tetrachloro-4',4',6',6'-tetrahydrospyro[12H-dibenzo[d,g]-[1,3,2]dioxaphosphocin-6,2'λ 5 -[1,3,5,2,4,6]-triazaphosphorine] Abstract: The condensation reactions of partly substituted spiro and ansa phenoxycyclotriphosphazenes 1 and 2 with tert-butylamine produce disubstituted geminal-bis(tert-butylamino)phenoxycyclotriphosphazene derivatives (3 and 4). The structures of these compounds were characterized by elemental analysis, and IR, 1 H-, 13 C-, 31 P-NMR and mass spectroscopic techniques. Compound 3 was also examined by X-ray crystallography and found to be crystallized in the monoclinic space group P2 1 /n with the unit cell parameters: a = = 10.842(4), b = 9.375(5), c = 29.104(11) Å, β = 99.25(3)°, V = 2920(2) Å 3 , D x = 1.404 g cm -3 .

“…From the distribution of the endocyclic torsion angles, it seems that in the central ring there are two local pseudo-mirrors, one running along the midpoints of the N1-P1 and N1 i -P1 i bonds, the other along the midpoints of the P2-N6 The ranges of the endocyclic P-N-P and N-P-N bond angles are 130.0(2) -133.2(2)˚ and 117.7(2) -121.6(2)˚, respectively, which can be compared with the corresponding ones. [3][4][5][6] Although the average value of the macrocyclic ring P-N bond distances is 1.584(3)Å, the average value of the other P-N bond lengths is 1.643(4)Å.…”

“…The four P atoms are coplanar and the four N atoms are displaced above (+) and below (-) their plane by equal amounts [N1 -0.570(4) and N6 -0.311(5)Å]. 4 The conformation of the macrocyclic ring is indicated by the torsion angles of the ring bonds in which the symmetry operation reverses the sign of a torsion angle (illustrated in Fig. 3).…”
