Gold-catalyzed direct alkynylation of tryptophan in peptides using TIPS-EBX

Jérôme Waser, Jonathan Brand, Gergely Laszlo Tolnai

The selective functionalization of peptides containing only natural amino acids is important for the modification of biomolecules. In particular, the installation of an alkyne as a useful handle for bioconjugation is highly attractive, but the use of a car ...

The influence of interunit carbon–carbon linkages during lignin upgrading

Jeremy Luterbacher, Li Shuai, Masoud Talebi Amiri

The cleavage of β-O-4 linkages in lignin can generate monomers with a phenyl propane structure that can easily be upgraded into valuable hydrocarbon biofuels and renewable aromatic chemicals. High-yield lignin monomer production from extracted (or technica ...

Modern computational approaches for quantifying inter- and intramolecular interactions

Jérôme Florian Gonthier

This thesis introduces modern computational approaches for quantifying and analyzing both intra- and intermolecular interactions. An original formalism to quantify intramolecular interactions ab initio is first introduced. Inspired from intermolecular Symm ...

Hydrogen evolution catalyzed by MoS3 and MoS2 particles

Xile Hu, Heron Vrubel, Daniel Andreas Merki

Amorphous MoS3 particles are prepared using a simple chemical method. Several deposition techniques are developed to fabricate electrodes loaded with MoS3 particles. These electrodes are highly active for hydrogen evolution. The catalytically active specie ...

Towards the development of a hydrogen battery

Gabor Laurenczy

A novel Ru-catalyzed hydrogenation of carbon dioxide proceeds with an unprecedented high formic acid to amine ratio (AAR of 2.69), which results in an improved energy content. The presented catalyst system allows for reversible fast hydrogen loading (even ...

Efficient Synthesis of beta-Chlorovinylketones from Acetylene in Chloroaluminate Ionic Liquids

Paul Joseph Dyson, Dennis Snelders

A method for the Friedel-Crafts-type insertion reaction of acetylene with acid chlorides in chloroaluminate ionic liquids is presented. The use of Ionic liquids not only serves to avoid the use of carbon tetrachloride or 1,2-dichloroethane but also suppres ...

Effects of short-term ecosystem experimental warming on water-extractable organic matter in an ombrotrophic Sphagnum peatland (Le Forbonnet, France)

Alexandre Buttler, Vincent Eric Jules Jassey

In a future warmer world, peatlands may change from a carbon sink function to a carbon source function. This study tracks changes in water-extractable organic matter (WEOM) after 1 year of in situ experimental warming using open top chambers (OTCs). WEOM w ...

A Well-Defined Ni Pincer Catalyst for Cross Coupling of Non-Activated Alkyl Halides and Direct C-H Alkylation

Oleg Vechorkin

Carbon-carbon bond forming reactions are among the most important and useful methods for organic synthesis. During the last years, significant progress has been made in this field. Whereas many catalysts were developed for the coupling of aryl, alkenyl, an ...

[(Methylcarbamothioyl)disulfanyl]methyl N-methylcarbamodithioate

The title compound, C5H10N2S5, was unintentionally obtained as the product of an attempted synthesis of a methyl-carbamodithioic acid using methylamine and carbon disulfide. In the molecule, two dithiocarbamate groups are bridged by a -CH2S- unit. The C-S- ...

Reactivity of a rhenium hydroxo-carbonyl complex toward carbon disulfide: insights from theory

Pablo Campomanes Ramos

The reaction mechanism on the formation of the hydrosulfido complex [Re(SH)(CO)(3)(bipy)] via the reaction of [Re(OH)(CO)(3)(bipy)] with carbon disulfide was theoretically investigated at the B3LYP/6-31+G(d, p) (LANL2DZ+f for Re) level of theory taking int ...
