Abstract

International audience; Notably available from the cellulose contained in lignocellulosic biomass, glucose is a highly attractive substrate for eco-efficient processes towards high-value chemicals. A recent strategy for biomass valorization consists on combining biocatalysis and chemocatalysis to realise the so-called chemo-enzymatic or hybrid catalysis. Optimisation of the glucose conversion to 5-hydroxymethylfurfural (HMF) is the object of many research efforts. HMF can be produced by chemo-catalyzed fructose dehydration, while fructose can be selectively obtained from enzymatic glucose isomerization. Despite recent advances in HMF production, a fully integrated efficient process remains to be demonstrated. Our innovative approach consists on a continuous process involving enzymatic glucose isomerization, selective arylboronic-acid mediated fructose complexation/transportation, and chemical fructose dehydration to HMF. We designed a novel reactor based on two aqueous phases dynamically connected via an organic liquid membrane, which enabled substantial enhancement of glucose conversion (70%) while avoiding intermediate separation steps. Furthermore, in the as-combined steps, the use of an immobilized glucose isomerase and an acidic resin facilitates catalyst recycling

13. Ring-opening polymerization of [epsilon]-caprolactone catalyzed by sulfonic acids: computational evidence for bifunctional activation

Abstract

The mechanism of ring-opening of [epsilon]-caprolactone by methanol catalyzed by trifluoromethane and methane sulfonic acids is analyzed, where the sulfonic acid has behaved as a bifunctional catalyst. The ring-opening has involved the cleavage of the endo C-O bond of the tetrahedral intermediate with concomitant proton transfer, where the sulfonic acid has acted as a proton shuttle via its acidic hydrogen atom and basic oxygen atoms.

17. Ru-(Mn-M)OX Solid Base Catalysts for the Upgrading of Xylitol to Glycols in Water.

Abstract

A series of Ru-(Mn-M)OX catalysts (M: Al, Ti, Zr, Zn) prepared by co-precipitation were investigated in the hydrogenolysis of xylitol in water to ethylene glycol, propylene glycol and glycerol at 200 °C and 60 bar of H2. The catalyst promoted with Al, Ru-(Mn-Al)OX, showed superior activity (57 h-1) and a high global selectivity to glycols and glycerol of 58% at 80% xylitol conversion. In comparison, the catalyst prepared by loading Ru on (Mn-Al)OX, Ru/(Mn-Al)OX was more active (111 h-1) but less selective (37%) than Ru-(Mn-Al)OX. Characterization of these catalysts by XRD, BET, CO2-TPD, NH3-TPD and TEM showed that Ru/(Mn-Al)OX contained highly dispersed and uniformly distributed Ru particles and fewer basic sites, which favored decarbonylation, epimerization and cascade decarbonylation reactions instead of retro-aldol reactions producing glycols. The hydrothermal stability of Ru-(Mn-Al)OX was improved by decreasing the xylitol/catalyst ratio, which decreased the formation of carboxylic acids and enabled recycling of the catalyst, with a very low deactivation.

Abstract

Polycaprolactone/polytrimethylenecarbonate copolymers of differentmicrostructures have been prepared in toluene solution under mildconditions by controlled ring-opening polymerization of ε-caprolactoneand trimethylene carbonate with methanesulfonic acid as catalyst.Sequential addition of the monomers led to the formation of well-defineddi- and tri-block copolymers, demonstrating the ability of the catalyticsystem to cross-propagate. Simultaneous copolymerization yielded gradientcopolymers as a result of the different copolymerization reactivityratios and absence of undesirable redistribution reactions. DSC analysesshowed a noticeable impact of the copolymer microstructure on thethermal properties. [ABSTRACT FROM AUTHOR]

28. Formation of a peri-Bridged Phosphonio-Naphthalene by Cu-Mediated Phosphine-Aryl Coupling.

Author

Blons C, Duval M, Delcroix D, Olivier-Bourbigou H, Mallet-Ladeira S, Sosa Carrizo ED, Miqueu K, Amgoune A, and Bourissou D

Abstract

The peri-iodo naphthyl phosphine 1 reacts with CuI to give the peri-bridged phosphonio-naphthalene 2, which has been fully characterized (multi-nuclear NMR, MS, XRD). The outcome of the reaction differs markedly from that observed with gold. A two-step pathway involving P-assisted C-I oxidative addition to copper, followed by P-C reductive elimination is shown to be energetically feasible by DFT calculations., (© 2018 Wiley-VCH Verlag GmbH & Co.
