The Reactions of Octachlorocyclotetraphosphazene with Difunctional Bis(2-Hydroxyethyl) Ether. Nuclear Magnetic Studies of the Products

GRAPHICAL ABSTRACT

Abstract

The reactions of octochlorocyclotetraphosphazatetraene, N₄P₄Cl₄ (1) with difunctional bis(2-hydroxyethyl) ether gave the following isolated and characterized products: one mono-spiro, N₄P₄Cl₆[(OCH₂)₂-(CH₂)₂O] (4); its isomers 1,3- (5) and 1,5-ansa (6); two isomeric cis-bis- and trans-bis-spiro, N₄P₄Cl₄[(OCH₂)₂-(CH₂)₂O]₂ (7 and 8); their isomers cis-1,3;5,7-ansa (9), cis-1,5;5,7-ansa (10), and spiro-ansa (11); as well as one bis-spiro mono-ansa, N₄P₄Cl₂[(OCH₂)₂-(CH₂)₂O]₃ (12), and a tetrakis, N₄P₄[O(CH₂)₂O(CH₂)₂O]₄ (13) derivatives. ³¹P, ¹H, and ¹³C NMR spectroscopic investigations indicated all bis(2-hydroxyethyl) ether substituted cyclochlorophosphazene derivatives to have four types of spectra: A₂MX (A₂BX), AA’XX’ (AA’BB’), A₂×₂ (A₂B₂), and A₄.
