Valorization of unsaturated dicarboxylic acids obtained from bio-fermentation of organic municipal wastes

Résumé

A stable and repeatable protocol has been developed to convert bio-sourced unsaturated diesters into mercaptans diesters using a thio-Michael catalysed reaction showing strong different reactivities when comparing monounsaturated dicarboxylic acids with conjugated diunsaturated counterparts. Additionally, new approach based on thiourea addition was developed showing complete conversion into MSA when using maleic acid. With cis,cis-muconic acid, thiourea works as an efficient catalyst for the isomerization into trans,trans-muconic acid opening a green alternative way to produce PET polymers.
