Sustainable access to renewable N-containing chemicals from reductive amination of biomass-derived platform compounds

“…Scheme 8Reaction pathway for the synthesis of N-substituted-5-methyl-2-pyrrolidones from the reductive amination of LA[111] …”

“…Starting from LA or its esters, a -pyrrolidones could become accessible[110]. Especially, N-substituted-5-methyl-2-pyrrolidones, derived from the reductive amination of LA or its esters, are an important class of chemicals extensively applied in pharmaceuticals, surfactants, agrochemicals and dispersants and as commodity solvents in organic synthesis[111][112][113]. As depicted in Scheme 8, a three-step -pyrrolidone, but the former reaction pathway is prevailing in recent studies.…”

Advancements and Complexities in the Conversion of Lignocellulose Into Chemicals and Materials

“…In the absence of any IL, the catalyst could be selectively confined (suspended) in the hydrocarbon medium, on condition that the aqueous solution was acidic in a pH range of 2.5-3. Ru-leaching in water was neglectable (Ru < 0.01% w/w) (Bellè et al, 2019).…”

Sustainable and Environmental Catalysis

“…In this context, with the aim to eliminate environmental pollutants (NO x , CO, SO x , VOCs) and to design new catalytic routes for clean energy production, environmental and sustainable catalysis represents a noble and one of the most investigated research directions. Moreover, as recently suggested, sustainable and environmental catalysis allows for converting waste in value-added products, and the degradation of pollutants through catalytic combustion/photocatalysis are considered main topics in this context [2,3]. As a matter of fact, it is worth highlighting some recent research advances.…”
