Investigation of nucleophilic substitution pathway for the reactions of 1,4-benzodioxan-6-amine with chlorocyclophosphazenes

“…A and 4-B). These results showed that the substituent effects on bond parameters of P 3 N 3 ring were proportional to the number of substituents on the same phosphorus atom and it could be attributed to electron-releasing character of 1,4-benzodioxan-6-amino groups comparing to withdrawing chlorine substituent [43][44][45]. All of these observations were compatible with the previous studies in the literature [16,20,43,46].…”

All of these observations were compatible with the previous studies in the literature [16,20,43,46]. Compounds 7a (2-trans-4) and 7c (2-trans-6) were structural isomers in which the eight-membered cyclotetraphosphazene ring (P 4 N 4 ) was non-geminal bis-substituted with two 1,4-benzodioxan-6-amino-moieties on two sequential phosphorous atoms (P1 and P2) in compound 7a while on two diagonal phosphorous atoms (P1 and P3) in compound 7c (Figs.…”

New organotin(IV) complexes with a potentially multi-site ligand based on the cyclotriphosphazene platform: Synthesis and spectral studies

“…2,2-Spiro(N-methylethanolamino)-4,4,6, 6-tetrachlorocyclotriphosphazene, N 3 P 3 (MeNC 2 H 4 O)Cl 4 , was prepared applying the literature method [23]. The IR spectra were obtained using an FT BOMEM MB102 spectrophotometer.…”

The first substitution reactions of N,N-spiro bridged octachlorobiscyclotriphosphazene

“…Although the bond lengths and bond angles of the cyclotriphosphazene rings, (PN) 3 , of all compounds (2-6) are found within the normal range for many cyclotriphosphazenes [38][39][40], there are small differences in the P-N bond lengths and N-P-N bond angles because of the substitution by the 1,2-ethanedioxy moiety.…”
