Metal-Free Synthesis of π-Conjugated Polyisoxazoles by 1,3-Dipolar Cycloaddition of Divanillin-Based Nitrile N-Oxides and Dialkynes

Abstract

Front Cover: A polyisoxazole is synthesized through an environmentally friendly approach using a nitrile N-oxide derived from vanillin, a representative aromatic biomass, and diethynylbenzene.
