The influence of a 5 M ethereal LiClO4 solution as solvent on the addition of different alkyl Grignard and alkynyllithium reagents to highly enolizable ketones was studied.A comparison with the results in the presence of CeCl3 shows a similar improvement in the yield. - Keywords: Nucleophilic addition; Lewis acid; Enolizable ketones; Alkyl Grignard; Alkynyllithium reagent

In the presence of anhydrous cerium(III) chloride, Grignard reagents react with ketones to afford addition products in high yields, even though the substrates are susceptible to abnormal reactions with Grignard reagents alone.
