A series of Pd-complexes containing nonsymmetrical bis(aryl-imino)acenaphthene (Ar-BIAN) ligands, featured by substituents on the meta positions of the aryl rings, have been synthesized, characterized and applied in CO/vinyl arene copolymerization reactions. Crystal structures of two neutral Pd-complexes have been solved allowing comparison of the bonding properties of the ligand. Kinetic and mechanistic investigations on these complexes have been performed. The kinetic investigations indicate that in general ligands with electron-withdrawing substituents give more active, but less stable, catalytic systems, although steric effects also play a role. The good performance observed with nonsymmetrical ligands is at least in part due to a compromise between catalyst activity and lifetime, leading to a higher overall productivity with respect to catalysts based on their symmetrical counterparts. Additionally, careful analysis of the reaction profiles provided information on the catalyst deactivation pathway. The latter begins with the reduction of a Pd(II) Ar-BIAN complex to the corresponding Pd(0) species, a reaction that can be reverted by the action

“…In contrast to the intensive efforts devoted to ethene (E)-carbon monoxide (ECO) copolymerization, much less has been reported on terpolymerization of two olefins with carbon monoxide [1][2][3][4][5][6][7][8][9][10][11][12], although industries have shown more interest for terpolymers than for copolymers, as documented by the high number of patents in this field. This is because the ECO copolymer is a highly crystalline material with high melting point (T m ), whereas the terpolymers have lower melting points, making them more easily processable [13][14][15][16][17][18][19].…”

a b s t r a c tThe [PdCl 2 (dppf)] complex efficiently catalyzes the terpolymerization of propene and ethene with carbon monoxide in HCOOH-H 2 O as a solvent, when H 2 O concentration ranges between 50 and 65 molar %. The productivity, the melting temperature and the viscosity average molecular weight of the terpolymer depend on the propene concentration and on the reaction time.The NMR analysis of the polymer composition indicates the presence along the chain mainly of ethene-CO units together with a low percent of propene-CO units.A reaction mechanism is proposed and discussed.
