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 reaction of n-, sec-, and tert-butyllithium with CO at atmospheric pressure at -110 and -135-degrees-C in the appropriate solvent system in the presence of ketones and aldehydes generates the acyllithium, RC(O)Li, which reacts with the carbonyl compound to give the alpha-hydroxy ketone, generally in good yield. Reactions with aldehydes are limited in scope, working well with the t-BuLi-derived acyllithium reagents, but not with n-BuC(O)Li.
