A synthetic, catalytic and theoretical investigation of an unsymmetrical SCN pincer palladacycle [PDF]
The SCN ligand 2-{3-[(methylsulfanyl)methyl]phenyl}pyridine, 1, has been synthesized starting from an initial Suzuki–Miyaura (SM) coupling between 3-((hydroxymethyl)phenyl)boronic acid and 2-bromopyridine.

Ligand Lone-Pair Influence on Hydrocarbon C-H Activation: A Computational Perspective [PDF]
Mid to late transition metal complexes that break hydrocarbon C-H bonds by transferring the hydrogen to a heteroatom ligand while forming a metal-alkyl bond offer a promising strategy for C-H activation.

A catalytic cycle for oxidation of tert-butyl methyl ether by a double C−H activation-group transfer process [PDF]
A square-planar, iridium(I) carbene complex is shown to effect atom and group transfer from nitrous oxide and organic azides, releasing the corresponding formate or formimidate and an iridium(I)−dinitrogen adduct.

Intra- and Intermolecular C−H Activation by Bis(phenolate)pyridineiridium(III) Complexes [PDF]
A bis(phenolate)pyridine pincer ligand (henceforth abbreviated as ONO) has been employed to support a variety of iridium complexes in oxidation states I, III, and IV.

Direct Aniline Formation with Benzene and Hydroxylamine
A single-step method for aniline formation was examined. Using a vanadate catalyst with an iron oxide co-catalyst and hydroxylamine hydrochloride as the amine source, an up to 90% yield of aniline was obtained with high selectivity.
