Palladium (0)-catalyzed allylic substitution reactions employing triorganoindium reagents have been investigated. In situ generated vinyl- and arylindiums react with substituted and unsubstituted cyclohex-2-enyl esters in the presence of 1-3 mol % Pd-2(dba)(3) to produce vinyl- or arylcyclohexenes in moderate to excellent yields. The stereoselectivity of this process was also examined, and evidence is presented that the reaction proceeds with inversion of stereochemical configuration.

Conditions for metalation of a variety of cyclic vinylethers and reaction of the resulting carbanions with electrophiles are described. Effects of the vinylether structure on the relative rates of metalation are discussed. Applications of this methodology to the construction of various types of carbonyl compounds are presented.
