Catalyst support and solvent effects during lignin depolymerization and hydrodeoxygenation

Jeremy Luterbacher, Florent Emmanuel Héroguel

We studied and compared the hydrodeoxygenation (HDO) and depolymerization of aldehyde-stabilized lignin and 4-propylguaiacol (PG), a model lignin monomer. We demonstrated by liquid phase adsorption that PG HDO catalyzed by Ru/C can be achieved in isooctane ...

Switchable [3+2] and [4+2] Heteroannulation of Primary Propargylamines with Isonitriles to Imidazoles and 1,6-Dihydropyrimidines: Catalyst Loading Enabled Reaction Divergence

Qian Wang, Jieping Zhu, Shuo Tong

Isonitrile 1 due to its carbene-like reactivity serves generally as a one-carbon synthon in a diverse set of organic transformations. We report in this article that the isocyano group can also act as a polarized triple bond to undergo, as a two-atom syntho ...

Droplet-based microfluidics in drug discovery, transcriptomics and high-throughput molecular genetics

Christoph Merten

Droplet-based microfluidics enables assays to be carried out at very high throughput (up to thousands of samples per second) and enables researchers to work with very limited material, such as primary cells, patient's biopsies or expensive reagents. An add ...

Rotational disorder in lithium borohydride

LiBH4 has been discussed as a promising hydrogen storage material and as a solid-state electrolyte in lithiumion batteries. It contains 18.5 wt% hydrogen and undergoes a structural phase transition at 381K which is associated with a large increase in rotat ...

Rotational Motion in LiBH4/LiI Solid Solutions

Pascal Martelli

We investigated the localized rotational diffusion of the (BH 4)- anions in LiBH4/LiI solid solutions by means of quasielastic and inelastic neutron scattering. The (BH 4)- motions are thermally activated and characterized by activation energies in the ord ...

Lithium bromide-promoted three-component synthesis of oxa-bridged tetracyclic tetrahydroisoquinoline derivatives

Jieping Zhu

Heating a toluene soln. of an alpha -(isocyano)acetamide deriv., an aldehyde and a 3-(2-aminophenyl)propenoic acid (aniline) deriv. in the presence of lithium bromide at 60 Deg provides an oxa-bridged tetracyclic tetrahydroquinoline in good to excellent yi ...

Octahedral and Tetrahedral Coinage Metal Clusters: Is Three-Dimensional d-Orbital Aromaticity Viable?

The first quant. evidence for the viability of three-dimensional arom. clusters involving d-orbitals in pseudo-octahedral coinage metal cages M6Lie2 (M = Cu, Tag, Au) as well as in tetrahedral coinage metal cages M'4Li4 (M' = Cu, Ag) was obtained computati ...

Analysis of low oxidation state transition metal clusters by laser desorption/ionization time-of-flight mass spectrometry

Paul Joseph Dyson

A variety of homonuclear and heteronuclear transition metal carbonyl clusters have been analyzed by ultraviolet laser desorption/ionization time-of-flight mass spectrometry. The spectra were recorded in negative and positive ion modes, using both linear an ...

Strategies for the selective functionalization of dichloropyridines at various sites

Whereas 2,3-dichloropyridine and 2,5-dichloro-4-(lithiooxy)pyridine undergo deprotonation exclusively at the 4- and 2-positions, resp., optional site selectivity can be implemented with 2,5- and 3,4-dichloropyridine (which are attacked, depending on the ch ...

Diethyl oxomalonate as a three carbon synthon for synthesis of functionalized 1,1′-disubstituted tetrahydroisoquinoline

Jieping Zhu

Pictet–Spengler condensation of β-arylethylamine with diethyl oxomalonate provides an entry to highly functionalized 1,1′-disubstituted tetrahydroisoquinoline in high yield. Selective functionalization of two ester groups is demonstrated. Syntheses and fun ...
