ABSTRACT:
Binuclear iridium (I) phosphine complexes of the general formula: ##STR1## in which X is fluorine, chlorine, bromine or iodine, and ##STR2## is in each case a chiral bidentate diphosphine ligand. The complexes are particularly suitable as catalysts for the inter- or intramolecular asymmetric hydroamination of prochiral olefins.
