PHOSPHORUS-NITROGEN COMPOUNDS. PART 61¹. THE REACTIONS OF OCTACHLOROCYCLOTETRA-PHOSPHAZATETRAENE WITH ETHANEDIOL, 1,3-PROPANEDIOL AND 1,4-BUTANEDIOL. SYNTHETIC AND NUCLEAR MAGNETIC RESONANCE SPECTROSCOPIC INVESTIGATIONS

Abstract

Abstract The reactions of octachlorocyclotetraphosphazatetraene, N4P4CI8, with ethane diol did not yield any characterised products. Those with 1,3-propanediol and 1.4-butanediol gave the following isolated and characterised derivatives, N4P4Cl8–2x[O(CH2)nO]x: x = 1, n = 3, 4; x = 2, n = 3, 4 (2 isomers of each); x = 3, n = 3,4; x = 4, n = 4. 31P, 1H and 13C n.m.r. spectroscopic investigations showed all derivatives to have spiro structures. The isomeric bis derivatives have 2,2,4,4- and 2,2,6,6-structures.
