ScholarBank@NUS Repository. https://doi.org/10.1002/anie.200351273 | 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. | Source Title: | Angewandte Chemie - International Edition | URI: | http://scholarbank.nus.edu.sg/handle/10635/92879 | ISSN: | 14337851 | DOI: | 10.1002/anie.200351273 |
