摘要
The neutral and cationic complexes of formula [(CH3)(Cl)Pd((PP)-P-boolean AND(S))] and [(CH3)(CH3CN)Pd((PP)-P-boolean AND(S))]BF4 [(PP)-P-boolean AND(S) = Ph2PCH2P(S)Ph-2 (dppmS), Ph2P(CH2)(2)P(S)Ph-2 (dppeS)] have been synthesized, characterized and tested as catalysts in the alternating copolymerization of ethylene and carbon monoxide. Both neutral and cationic Pd(II) complexes show eta(2)-(P,S) coordination and cationic complexes exhibit moderate activity. (C) 2000 Elsevier Science S.A. All rights reserved.
