through a highly efficient and E-selective C–H activation/Heck/Aza-Wacker sequence. Substoichiometric amounts of benzoquinone can be employed in a cooperative oxidation system with O2, leading to facile purification of products. Modification of the reaction conditions provides a generalroute to substituted phthalimides by carbonylation with CO. Both systems were found to tolerate a wide range of functionality
