ABSTRACT:
Complexes of certain transition metals and phosphine or arsine ligands with carbon dioxide, e.g., (carbon dioxide)bis[1,2-ethanediyl-bis[dimethylphosphine]-P,P']iridium(1+), chloride, useful as catalysts in hydrogenation and isomerization, e.g., of 1-butene, are prepared by direct addition of pressurized CO.sub.2 to the appropriate metal complex precursor, e.g.,
