phenone oxime-derived palladacycles as catalysts under phosphine-free conditions. The reaction is succesfully carried out in organic solvents, such as DMF, in the presence of an organic base, such as dicyclohexylmethylamine, and with TBAB as additive at 120 °C under conventional or microwave heating. (E)-N-Styrylphthalimides are mainly obtained using a rather low palladium loading (0.05–1 mol%). Similar
