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, Loris Giovanni Lombardo, 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 ...

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 ...

Strain-Promoted C-C Bond Cleavages of Cyclobutanes : A Molecular Complexity Generating Tool

Laetitia Marie Mélanie Souillart

The catalytic activation of carbon-carbon single bonds is a major challenge in organometallic chemistry, since the lack of prefunctionalization steps opens the way to new, economically and ecologically attractive reaction pathways. Strained ring substrates ...

Sequential N–O and N–N Bond Cleavage of N-Heterocyclic Carbene-Activated Nitrous Oxide with a Vanadium Complex

Rosario Scopelliti, Kay Severin, Matthew Wodrich, Euro Solari, Alexander Tskhovrebov

Chemically induced bond cleavage of nitrous oxide typically proceeds by rupture of the N–O bond with concomitant O-atom transfer and liberation of dinitrogen. On a few occasions, N–N bond scission has been observed instead. We report a reaction sequence in ...
