Abstract

Abstract75 years after the discovery of hydroformylation, cobalt catalysts are now undergoing a renaissance in hydrogenation reactions. We have evaluated arene metalates in which the low‐valent metal species is—conceptually different from heteroatom‐based ligands—stabilized by π coordination to hydrocarbons. Potassium bis(anthracene)cobaltate 1 and ‐ferrate 2 can be viewed as synthetic precursors of quasi‐“naked” anionic metal species; their aggregation is effectively impeded by (labile) coordination to the various π acceptors present in the hydrogenation reactions of unsaturated molecules (alkenes, arenes, carbonyl compounds). Kinetic studies, NMR spectroscopy, and poisoning studies of alkene hydrogenations support the formation of a homogeneous catalyst derived from 1 which is stabilized by the coordination of alkenes. This catalyst concept complements the use of complexes with heteroatom donor ligands for reductive processes.

In the presence of 1 mol %1and 20 mol % 1 3‐diphenyl‐2‐propanol styrenes were hydrogenated much slower than with1(see the Supporting Information);
the oxidation of the catalyst by alcohols might also lead to partial formation of Co0nanoparticles. So far poisoning experiments with Hg and dct were not conclusive.

Dehydrogenations of ethyl dihydrocinnamate and 2‐ethylnaphthalene were not observed with 5 mol %1at 60 °C respectively. See Ref. [7b].
