Various unsymmetrical secondary or tertiary alcohols have been prepared in high yields by an efficient one-pot procedure involving the acylation of an organomanganese reagent by an acyl chloride and addition to the ketone formed of various organometallic compounds (RLi, RmgX, LiAlH4, NaBH4. The complexation of the intermediate ketone by the metallic salts present in the reaction mixture allows to perform
The rhodium-catalyzedaddition reactions of sodium tetraphenylborate and arylboronic acids to nitriles, ketones, and imines were examined. The reaction of nitriles could be carried out efficiently in the presence of a catalyst system of [RhCl(cod)]2–dppp and H2O to give the corresponding monoarylated products selectively. Although unactivated ketones and imines are known to be poor electrophiles for
