The copper(II) complexes of 3-methylpentane-2,4-dione and 2-methyl-1-phenylbutane-1,3-dione are good substrates for C-alkylation with several alkyl bromides including 1-bromoadamantane and 9-bromofluorene. Sterically congested β-diketones have been prepared.

Iron-catalysed 1,2-acyl migration of tertiary α-azido ketones and 2-azido-1,3-dicarbonyl compounds provides a simple and atom-economical approach toward enamides and isoquinolones. This paper reports two catalyst systems for these transformations which employ iron(ii) complexes [Fe(dpbz)]Br2 (dpbz = 1,2-bis(diphenylphosphino)benzene) and FeBr2/Et3N, respectively. [Fe(dpbz)]Br2 was found to be highly effective at converting 2-azido-2,3-dihydro-1H-inden-1-ones to isoquinolones. The reagent combination of FeBr2/Et3N, on the other hand, exhibited a broader catalytic scope, owing to the beneficial effect of Et3N. This latter catalyst system enables 2-azido-2-methyl-1,3-dicarbonyl compounds to be converted to the corresponding enamides under mild conditions in good yields.
Reactions of copper(II) β-diketonates under free radical conditions. Preparation of highly congested β-diketones

Copper(II) β-diketonates react with alkyl bromides under free radical conditions to give highly congested β-diketones such as 3-(1-adamantyl)-3-alkylpentane-2,4-diones. Another typical free radical reagent: benzoyl peroxide, reacts also functionalizing the intercarbonyl positions.
