From the reactions of hexachlorocyclotriphosphazatriene, N 3P3Cl6 (1) with pentane-1,5-diol (2) in dichloromethane solution, the following derivatives have been isolated: 2,2-spiro(1′,5′-pentanedioxy)-4,4,6,6- tetrachlorocyclotriphosphazatriene, N3P3Cl 3[O(CH2)2O] (3); its ansa isomer, 1,3-ansa(1′,5′-pentanedioxy)-1,3,5,5- tetrachlorocyclotriphosphazatriene, (4); bis spiro(1′,5′- pentanedioxy)-6,6-dichlorocyclotriphosphazatriene, N3P 3Cl2[O(CH2)5O]2 (5); its spiro-ansa isomer, (1′,5′-pentanedioxy)-1,3- dichlorocyclotriphosphazatriene (6); as well as the bino(1,5-pentanedioxy)-di- (pentachlorocyclotriphosphazatriene), N3P3Cl5 [O(CH2)5O]N3P3Cl5 (7), and tri-bino(1,5-pentanedioxy)-di (trichlorocyclotriphosphazatriene), N 3P3Cl3[O(CH2)5O] 3N3P3Cl3, (8) derivatives. Their structures were established by MS and NMR with the use of 1H, 13C, and 31P spectroscopy. Product types and relative yields are compared with those of the previously investigated diol derivatives. The yield of the mono-ansa product (25%) obtained in this system was considerably increased relative to those of the propane-1,3-diol derivative (11.2%) and decreased relative to the 2,2-dimethyl-propane-1,3-diol (36.2%), and bis(2-hydroxyethyl) ether (34.5%) derivatives. © 2013 Copyright Taylor and Francis Group, LLC.
