An efficient Pd-catalyzed cross-dehydrogenative coupling of heteroarenes with alkenes has been developed. This alkenylation paradigm encompasses a wide range of substrates and provides a straightforward approach toward C2-E-alkenylated azole motifs.

hydroheteroarylation of cyclicdienes via C–H bond activation of heteroarenes. In the presence of an N-heterocyclic carbene (NHC) ligand, hydroheteroarylation of cyclicdiene with azole afforded α-alkenyl-azole, forging a Heck-like product without using any external oxidant. Conversely, changing the ligand to PCy3 would switch this reaction manifold to afford the other isomeric β-alkenyl substituted azole.
