Abstract: Unsymmetrical aryl ketones undergo asymmetric hydrogenation in ionic-liquid media in the presence of (R)-binap and a rhodacarborane catalyst derived from the suicide precursor 1 (see scheme). Ketones that are poor substrates for other methods can be hydrogenated in quantitative yields with very high enantioselectivities (97.3-99.5% ee). The novel ionic liquid (N-n-butylpyridinium)+(closo-CB11H12) - provides a superior medium for these reactions.
