σ-Alkenyl endo-palladacycle formation via regiospecific functionalisation of an unreactive NHC-tethered C(sp(2))-H bond

An unusual cyclometallation reaction at palladium is described, which proceeds via C-H functionalisation of a vinylic C(sp(2))-H bond tethered to an NHC ligand. The energetic balance between palladacycle formation and bis-NHC complexation has been found to be very subtle.
