Synthesis of Novel Cyclic Poly(2,5-furylene vinylene) Biosourced Furanic Polymers via McMurry Homopolymerization of Diformylfuran

Abstract

The interest in synthesizing chemicals from renewable sources such as biomass has grown steadily in recent years to become the focus of a promising industry in developing more sustainable materials that overcome current dependence on fossil sources. Furan derivatives such as furfural (FA) and 5-hydroxymethylfurfural (HMF), which can be derived from pentose and hexose sugars, are key components of this new sector. HMF can be seen as the link between biomass chemistry and petrochemicals. By selective oxidation of the hydroxymethyl function of HMF, 2,5-diformylfuran (DFF) can be obtained, a substrate of industrial and scientific interest with a symmetrical structure in which aldehyde groups can be converted into other functions, such as olefins.In this paper, we report on synthesizing and characterizing a new cyclic polymeric material based on DFF obtained by the McMurry reaction.
