A variety of palladacycles are shown to catalyze Heck alkenylations with similar efficiencies. The new oxapalladacycle 1 was shown to insert and transmetalate under mild conditions with n-butyl acrylate and vinyltributylstannane, respectively. This palladacycle acts as an active (pre)catalyst for cross-coupling and Heck reactions.
