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

LiAlH4 Reduction of alpha-adamantyl (and tert-butyl)-beta-diketones occur under anti-Curtin-Hammett preequilibrium conditions, each preferred conformer leading to a different stereoisomeric diol, whereas reduction of 3-adamantyl-3-methyl (and ethyl)pentane-2,4-dione occurs with high diastereoselectivity to afford only the (2R, 3r, 4S) meso diol.

α-(1-Adamantyl)-β-dicarbonyl compounds are prepared by the reactions of the Co(II) complexes of β-dicarbonyl compounds with 1-bromoadamantane. This provides a route to the previously inaccessible 4-(1-adamantyl)-3.5-disubstituted pyrazoles and isoxazoles.
