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.
3-甲基戊烷-2,4-二酮和2-甲基-1-苯基丁烷-1,3-二酮的铜(II)络合物是用几种烷基溴化物(包括1-溴金刚烷和9-溴芴)进行C-烷基化的良好底物。已经制备了立体拥挤的β-二酮。
