Abstract: Abstract Polymerization reactions using renewable raw material as substrate (namely, δ-valerolactone) and N-heterocyclic carbenes (NHC) as organocatalysts to form polyesters were investigated by computational approaches. Two routes were investigated for the reaction, either with the… read more here.

Abstract: The questionable mechanism initially proposed to explain how 1,5,7-triazabicyclo[4.4.0]dec-5-ene (TBD) allows us to ring-open β-lactones, such as β-butyrolactone (BL), is reinvestigated here. With the use of a trisubstituted β-lactone, i.e. (R,S)-benzylcarbonyl-3,3-dimethyl-2-oxetanone, and the association of… read more here.
