Aerobic oxygenation/dehydrogenation of olefins and 14-dihydropyridines catalyzed by tris(tetrazolyl enolate)iron(III) complexes
TL;DR: In this article, the catalytic epoxidation of olefins by synthetic metalloporphyrin analogues associated with molecular oxygen in the presence of an electron source (isobutyraldehyde) is described.

Epoxidation of alkenes efficiently catalyzed by Mo salen supported on surface-modified halloysite nanotubes
Yu Long,Bing Yuan,Jiantai Ma +2 more
TL;DR: Halloysite-nanotube-supported Mo salen (HNTs-Mo-SL) catalysts were successfully prepared using a facile chemical surface modification and self-assembly method.
Journal ArticleDOI
Functionalization and Rearrangement of Spirocyclohexadienyl Oxindoles: Experimental and Theoretical Investigations
TL;DR: The proposed mechanism relies on a thermodynamically driven diisopropylamine-mediated proton transfer with the cleavage of the diene-amide C=O bond as the key step.

Influence of N-donor bases and the solvent in oxodiperoxomolybdenum catalysed olefin epoxidation with hydrogen peroxide in ionic liquids
Matthew Herbert,Francisco Montilla,Agustín Galindo,Raquel Moyano,Antonio Pastor,Eleuterio Álvarez +5 more
TL;DR: Of the bases investigated, pyrazoles were identified as the most efficient additive species and the best results were obtained using 3,5-dimethylpyrazole, and its structure determined by X-ray crystallography.
