The in situ generation of n-C4H9C(O)Li by the reaction of n-C4H9Li with CO at -110 deg C in the presence of ketones gives good (50-90percent) yields of α-hydroxy ketones.When the n-C4H9C(O)Li reaction is carried out in the presence of esters, good (65-80percent) yields of α-diketones are obtained, thus demonstrating that RC(O)Li can be reagents of practical utility.Similar reactions were observed with sec-C4H9Li and tert-C4H9Li.

The reaction of n-, sec-, and tert-butyllithium with CO at atmospheric pressure at -110 and -135 deg 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 α-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.
