Cyclohexa-2,4- and 2,5-dienones bearing position 2 or 4 a dihalomethyl group (halogen = chlorine or bromine) are smoothly reduced by tri-butyltin hydride to furnish appropriately substituted tropones.Modification of the substituents permits access to a tropolone and to less substituted tropones.The mechanism of this ring expansion process has been discussed.
