Synthesis of a Nanostructured Composite: Octakis(1-propyl-1H-1,2,3-triazole-4-yl(methyl 2-chlorobenzoate))octasilsesquioxane via Click Reaction

Abstract

Octakis(1-propyl-1H-1,2,3-triazole-4-yl(methyl2-chlorobenzoate))octasilsesquioxanes as functionalized silsesquioxanes were synthesized via click reaction (copper-catalyzed Huisgen 1,3-dipolar cycloaddition reaction) between azide-moiety functionalized silsesquioxane and prop-2-ynyl-2-chlorobenzoate. The latter one was synthesized via the condensation reaction of propargyl alcohol and 2-chloro benzoyl chloride in the presence of SBA-Pr-NH₂ as a nano basic catalyst. This approach provides a simple and convenient route to efficiently functionalize a wide range of new structures on the surface of silsesquioxanes.
