Combo deal: An aqueous solution of levulinicacid (LA) and formic acid (FA) derived from biomass‐based carbohydrates can be converted efficiently to pyrrolidines via a ruthenium catalyst without need for an energy‐intensive separation of LA or an external H2 source. The ruthenium catalyst combines two processes: decomposition of FA to H2 and reductiveamination of LA with an amine.
catalyst was developed to produce biomass-derived 5-methylpyrrolidone under room temperature and atmospheric hydrogen. The suitable mesoporous structure created high dispersion of Pt species and accelerated the reaction processes. The isomerization of imine to enamine on the catalyst made this conversion easy undermildconditions.
