Versatile Coordination Polymer Catalyst for Acid Reactions Involving Biobased Heterocyclic Chemicals

The chemical valorization/repurposing of biomass-derived chemicals contributes to a biobased economy. Furfural (Fur) is recognized platform produced from renewable lignocellulosic biomass, and furfuryl alcohol (FA) its most important application. aromatic aldehydes Fur benzaldehyde (Bza) are commonly found in the slate compounds via biomass pyrolysis. On other hand, glycerol (Gly) by-product industrial production biodiesel, derived fatty acid components biomass. This work focuses on catalyzed routes Fur, Bza, Gly FA, using versatile crystalline lamellar coordination polymer catalyst, namely [Gd(H4nmp)(H2O)2]Cl·2H2O (1) [H6nmp=nitrilotris(methylenephosphonic acid)] synthesized an ecofriendly, relatively fast, mild microwave-assisted approach (in water, 70 °C/40 min). first among polymers or metal-organic framework type materials studied for Fur/Gly Bza/Gly reactions, giving heterobicyclic products dioxolane dioxane, was also effective FA/ethanol reaction. 1 stable promoted target catalytic selectively leading dioxane reactions (up 91% 95% total yields respectively, at 90 °C/4 h), and, 2-(ethoxymethyl)furan ethyl levulinate heterocyclic FA.
