Reduction of metal salts with tetraalkylammonium hydrotriorganoborates in organic phases yields a very narrow size range of metal colloids of the elements of groups 6–11. Adsorbed on carrier surfaces, these colloids are highly active hydrogenation catalysts whose activity can be further increased by doping with low‐valent organotitanium compounds.
