Synthesis of 1,3,3,5,5-Penta[1-(2,2-dimethyl-1,3-dioxolan-4-yl)methoxy]-1-[(1 H -1,2,3-triazol-4-yl)alkoxy]cyclotriphosphazenes

Abstract

Based on 1,3,3,5,5-penta[1-(2,2-dimethyl-1,3-dioxolan-4-yl)methoxy]-1-chlorocyclotriphosphazene, a series of hybrid compounds was obtained by two-step synthesis. In the molecules of the compounds obtained, hydrophobic organic residues are attached to the cyclotriphosphazene nucleus via a linker. A dialkyl substituted 1,2,3-triazole synthesized by click-chemistry methodology from acetylenic cyclotriphosphazene derivatives and organic azides in the presence of Cu(I) can be used as a linker connecting pentadioxolane-substituted phosphazene core. The reaction proceeds regioselectively with the formation of 1,4-disubstituted 1,2,3-triazoles only.
