Goodman, D. Zeng, J. Optimizations to generate CuH in situ have led to an efficient and inexpensive hydrosilylation method for dialkyl ketones. Lee, Y. Liu, J. Seint-Dizier, P. Yuan, W. Liu, Y.

  • Alcohol synthesis by carbonyl compound reduction

  • Enantioselective ketone reductions convert prochiral ketones into chiral, non- racemic alcohols and are used heavily for the synthesis of stereodefined alcohols. Reductions of aldehydes and ketones follow the same selectivity models as the addition of unstabilized carbon nucleophiles to these functional.

    Asymmetric electroreduction of ketone and aldehyde derivatives was examined for two electrochemi- cal reduction systems using alcohol dehydrogenase (ADH) .

    Activation of diphenylsilane in the presence of a catalytic amount of an N-heterocyclic carbene NHC enables hydrosilylation of carbonyl derivatives under mild conditions. Jennings, J.

    After hydride transfer, complex III releases the product and coordinates a second molecule of borane. Pardo, J.

    The use of diethylaluminum benzenethiolate enables an efficient discrimination between aldehydes and other carbonyl functions and allows a chemoselective in situ reduction of ketones and methyl esters in the presence of aldehydes without using traditional protecting group methodologies.

    Bae, S. Zhang, Synlett, Shin, J. These robust lanthanide catalysts exhibited high reactivity with low catalyst loadings under mild conditions, good functional group tolerability, and unique carbonyl-selectivity.

    In contrast, we reported the use of (PPh3)2Re(O)2I as a catalyst in the hydrosilylation of aldehydes and ketones – an overall reduction of these. Asymmetric reduction of prochiral ketones is one of the most important methods for the synthesis of chiral secondary alcohols and constitutes a.
    Nishibayashi, S. A family of chiral iminophenyl oxazolinylphenylamines IPOPA ligands enables an efficient cobalt-catalyzed asymmetric hydrosilylation of simple ketones with a low catalyst loading of CoCl 2 to afford chiral alcohols in good yields with high enantioselectivities.
