and a slight excess of methyl acrylate, the products were surprisingly the bis(ligand)palladium complexes [Pd(κ2-L3)2][BAr4]2 (13) and [Pd(κ2-L4)2][BAr4]2 (14) instead of the expected acylpalladium chelate complexes ([(κ2-L)Pd(CH2)2C(O)OMe}][BAr4]). Complexes 1–6, activated with Na[BAr4], and pre-activated complexes 7–12 at 10 bar of ethylene and 30 bar of carbon monoxide produced polyketones, albeit
