A highly regioselectiveoxidative coupling reaction between indolizines and vinylarenes has been accomplished in the presence of palladium catalysts to give only the branched α-product in high efficiency. The regioselectivity is promoted significantly by bidentate nitrogen ligands.

A Pd/Cu-catalyzed dehydrogenative Heck coupling is established that allows direct alkenylation of various biologically relevant N-heteroarenes with alkenes. The resulting π-extended alkenylated N-heteroarenes exhibit interesting fluorescent properties and have proven to be potentially useful fluorescent probes for bioimaging.
