Abstract
The synthesis of a zwitterionic Pd(II) complex supported by an anionic bis(phosphino)borate ligand, Ph_(2)B(CH_(2)PPh_(2))_(2) (abbreviated as [Ph_(2)BP_(2)]), is reported. The new complex, [Ph_(2)BP_(2)]PdMe(THF), is active for CO and ethylene copolymerization. The copolymerization activity and polyketone molecular weight for the neutral, zwitterionic system are compared with those for the cationic systems [R2E(CH2PPh2)2PdMe(THF)][B(C_(6)F_(5))_(4)] where ER_(2) = SiPh_(2) and CH_(2). Surprisingly, the more electron rich zwitterionic system is a catalyst of activity comparable to that of the more conventional cationic systems.
