The reactions of cyclotriphosphazene with 2-(2-hydroxyethylamino)ethanol. Spectroscopic studies of the derived products

Abstract

The reactions of cyclotriphosphazene (1) with 2-(2-hydroxyethylamino)-ethanol (2) were investigated. 2-(2-hydroxyethylamino)-ethanol (2) is a tri-functional reagent consisting of both aliphatic hydroxyl and the secondary amino groups and its nucleophilic substitution reactions with cylotriphosphazene can lead to different product types; open chain, spiro, ansa, bridged and their mixtures. The reactions with one, two and three equimolar ratios of 2-(2hydroxyethylamino)-ethanol, in the presence of NaH at 0-10 0 C and at room temperature gave

“…Due to the increasing demand for modern materials with improved performance, interest in organic–inorganic cyclic systems and polymers is growing. Among them, cyclic compounds containing phosphorus and nitrogen [ 1 , 2 , 3 , 4 , 5 ]; phosphorus and oxygen [ 6 ]; boron and oxygen [ 7 , 8 ]; nitrogen, oxygen, and silicon [ 9 ] atoms; nitrogen-containing heterocyclic compounds based on imidazole and guanidine [ 10 ], including proton sponges, linear siloxanes, and phosphazenes [ 11 , 12 , 13 ]; organotin polymers [ 14 ]; and copper-containing coordination polymers [ 15 ] should be noted. Researchers continue to find new applications for such compounds.…”
