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.

By reacting, using as a catalyst a modified or unmodified cyclodextrin, a phenol compound with a haloform in the presence of an alkali metal hydroxide, while maintaining the molar ratio of the cyclodextrin to the haloform at 0.5 to 10, a substituent group
A Simple Synthesis of the Tropone Nucleus

Reduction of suitably substituted dichloro- or dibromo-methylcyclohexadienones with tributyltin hydride affords tropones (or tropolones) in medium to excellent yield; ortho- and para-substituted cyclohexadienones afford the same tropone.
