Abstract
A novel process is described for preparing low valent Group VIII metal hydrides, useful as catalysts in the hydrogenation of a large variety of organic compounds, in which a low valent Group VIII metal halide complex, such as (Ph.sub.3 P).sub.3 RhCl, is reacted with an alkali or alkaline earth metal alkylamide, such as LiN(CH.sub.3).sub.2, containing at least one alkyl group having an alkyl hydrogen atom in the beta position with respect to the metal atom. The metal alkylamide functions both as a dehalogenating and hydrogenating agent in the process. The process can be conducted at room temperature in a suitable organic solvent under an inert atmosphere utilizing the metal alkylamide in stoichiometric quantities. The process is also useful in preparing zero valent Group VIII metal complexes, such as (Ph.sub.3 P).sub.4 Pd.degree..
