Tuning the reactivity of uranium towards small molecules in multimetallic complexes

One of the main goals of organometallic chemistry in the last decades was the activation of small molecule in mild reaction conditions. Even though multiple examples of catalytic cycles able to produce fine chemicals from cheap and abundant sources using t ...

C-C bond activation enabled by dyotropic rearrangement of Pd(iv) species

Qian Wang, Jieping Zhu, Hua Wu, Jian Cao

The weak carbon-metal bond combined with the kinetic inertness of the carbon-carbon bond renders metal-catalysed C-C bond activation to be highly challenging. Most of the reported C-C bond activation methodologies involve strain-releasing cleavage of small ...

Interfacial Effect between Aluminum-Based Complex Hydrides and Nickel-Containing Porous Carbon Sheets

Andreas Züttel, Emad Oveisi, Heena Yang, Mo Li, Youngdon Ko

Supported aluminum-based complex hydrides (alanates) were investigated in view of their interaction at the interface. Nickel-containing porous carbon sheets (Ni-PCSs) were combined with various alanates, resulting in a decrease of the decomposition tempera ...

Catalyst design for C-O bond hydrogenolysis of renewable materials.

Antoine Philippe Van Muyden

Anthropogenic carbon dioxide emissions leading to climate change require to use of renewable carbon sources such as CO2 and biomass which differ from fossil resources by having a higher number of oxygen atoms. Therefore, catalytic C-O bond cleavage will pl ...

X-ray absorption linear dichroism at the Ti K edge of anatase TiO2 single crystals

Majed Chergui, Oliviero Cannelli, Giulia Fulvia Mancini, Thomas Charles Henry Rossi, Camila Bacellar Cases Da Silveira, Dominik Kinschel, Jérémy Raymond Jean Maurice Rouxel

Anatase TiO2 (a-TiO2) exhibits a strong x-ray absorption linear dichroism in the pre-edge, the XANES and the EXAFS at the titanium K edge. In the pre-edge region, the behavior of the A1-A3 and B peaks originating from the 1s - 3d transitions is due to the ...

Water-assisted oxygen activation during gold-catalyzed formic acid decomposition under SCR-relevant conditions

Davide Ferri, Oliver Kröcher

Owing to the problems associated with the use of urea as an ammonia precursor compound in the selective catalytic reduction process in automobiles, alternative compounds such as ammonium formate, methanamide, and guanidinium formate have been suggested as ...

Catalytic Enantioselective Transformations Involving C-H Bond Cleavage by Transition-Metal Complexes

Nicolai Cramer, Shouguo Wang, Christopher Gordon Newton, Caio Costa Oliveira

The development of new methods for the direct functionalization of unactivated C-H bonds is ushering in a paradigm shift in the field of retrosynthetic analysis. In particular, the catalytic enantioselective functionalization of C-H bonds represents a high ...

Enantioselective Total Synthesis of (−)-Terengganensine A

Qian Wang, Jieping Zhu, Cyril Piemontesi

A seven-step enantioselective total synthesis of (-)-terengganensine A, a complex heptacyclic monoterpene indole alkaloid, was accomplished. Key steps included: a) Noyori's catalytic enantioselective transfer hydrogenation of the iminium salt to set up the ...

Understanding the anomalous behavior of Vegard's law in Ce1-xMxO2 (M = Sn and Ti; 0 < x

Olga Safonova

The dependence of the lattice parameter on dopant concentration in Ce1-xMxO2 (M = Sn and Ti) solid solutions is not linear. A change towards a steeper slope is observed around x similar to 0.35, though the fluorite structure (space group Fm3m) is preserved ...

N-N Bond Cleavage in a Nitrous Oxide-NHC Adduct Promoted by a PNP Pincer Cobalt(I) Complex

Kay Severin

The reactivity of a PNP cobalt(I) complex towards the nitrous oxide N-heterocyclic carbene adduct (NHC-N2O) was explored. Several products were isolated including the cobalt nitrosyl complex (HPNP)Co(NO) (1) and the NHC-derived imine NHC=NH (2). This study ...
