Description
Summary:Herein, we report a new synthetic approach to produce renewable polymers in which all carbons come from renewable sources, with the exploration of formamide reactivity as the key step for a process with 100% atom economy. The first step is the fast production of renewable monomers via a photocatalytic reaction under continuous flow conditions (tR = 1-5 min). Formamide (HCONH2), renewable acrylate derivatives and tetrakis(tetrabutylammonium)decatungstate as photocatalyst (TBADT) enabled us to produce the desired renewable monomers with excellent yields (up to 98%). For the final step, a polycondensation reaction with biobased diols produced novel polyesters, which exhibit a structurally diverse structure with a succinimide unit.
