Abstract

Cobalt stearate and alkylmagnesium halides react to form a dark brown homogeneous solution which catalyses the hydrogenation of olefins at Mg:Co ratios of 3-8:1. Cobalt was shown to be present in the form of a complex dihydride LxCoH2, formed, presumably, by unstable cobalt alkyls splitting off the alkyl group in the form of an olefin. Besides having cataltic activity, this complex cobalt hydride stoichiometrically hydrogenates alkenes to alkanes. Unsaturated alkoxy-magnesium halides formed from the stearate group are proposed as ligands ensuring the solubility of the complex hydride in hydrocarbon-ether mixtures.
