General Description

Cyclopentylbenzene, also known as benzocyclopentane, is a chemical compound consisting of a cyclopentyl group attached to a benzene ring. It is a colorless liquid with a very faint odor, and it is commonly used as a solvent in the manufacturing of various products, including dyes, perfumes, and pharmaceuticals. Cyclopentylbenzene is also used as an intermediate in the production of other organic compounds. It is important to handle this chemical with care, as it may be harmful if ingested, inhaled, or absorbed through the skin. Proper safety precautions should be taken when handling and storing cyclopentylbenzene to prevent any potential health risks.

Cobalt-Catalyzed Hydrogenations via Olefin Cobaltate and Hydride Intermediates

Redox noninnocent ligands are a promising tool to moderate electron transfer processes within base-metal catalysts. This report introduces bis(imino)acenaphthene (BIAN) cobaltate complexes as hydrogenation catalysts. Sterically hindered trisubstituted alkenes, imines, and quinolines underwent clean hydrogenation under mild conditions (2-10 bar, 20-80 °C) by use of the stable catalyst precursor [(DippBIAN)CoBr2] and the cocatalyst LiEt3BH. Mechanistic studies support a homogeneous catalysis pathway involving alkene and hydrido cobaltates as active catalyst species. Furthermore, considerable reaction acceleration by alkali cations and Lewis acids was observed. The dinuclear hydridocobaltate anion with bridging hydride ligands was isolated and fully characterized.

Olefin-Stabilized Cobalt Nanoparticles for C=C, C=O, and C=N Hydrogenations

The development of cobalt catalysts that combine easy accessibility and high selectivity constitutes a promising approach to the replacement of noble-metal catalysts in hydrogenation reactions. This report introduces a user-friendly protocol that avoids complex ligands, hazardous reductants, special reaction conditions, and the formation of highly unstable pre-catalysts. Reduction of CoBr2 with LiEt3BH in the presence of alkenes led to the formation of hydrogenation catalysts that effected clean conversions of alkenes, carbonyls, imines, and heteroarenes at mild conditions (3 mol % cat., 2–10 bar H2, 20–80 °C). Poisoning studies and nanoparticle characterization by TEM, EDX, and DLS supported the notion of a heterotopic catalysis mechanism.
