A practical method for the conversion of 1,2-disubstituted cyclopropanols derived from Kulinkovich cyclopropanation into linearenones was developed. The approach features regioselective cleavage of the cyclopropane rings in EtOH at ambient temperature with inexpensive and readily available Co(acac)2 as the catalyst and air as the reagent. The crude intermediate peroxides were directly reduced with
