Selective one-pot functionalization of methyl n-alkyl ketones, CnH2n+1COMe (n = 6–8) involving C-sp3–H bond cleavage with CO and various nucleophilic substrates [iPrOH, BuCH(Et)CH2OH, CF3CH2OH, (CF3)(Me)CHOH, H(CF2)2CH2OH, HCCCH2OH, furan, thiophene, and anisole] in the presence of the superelectrophilic system CBr4·2AlBr3 has been performed for the first time.
