Cobalt-mediated alkylation of β-dicarbonyl compounds. Electrochemical evidence of cobalt(l) intermediate species and HPLC-MS detection of reaction intermediates

Research output: Contribution to journalArticleResearchpeer-review

Abstract

The alkylation reactions of Co(II) acetylacetonate with alkyl halides are triggered by electrochemical reduction of the complex. This confirms Co(I) species as intermediates. HPLC-MS analysis of the reaction mixtures has permitted identification of some cobalt-containing intermediates involved in the alkylation reactions. Based on these results we propose a mechanistic hypothesis for the formation of dialkylation products and Co(III) acetylacetonate. © Springer-Verlag Ibérica 1997.
