Electrospray mass spectrometric study of homogeneous catalytic system Pd(CF3COO)(2)-Ph(2)P(CH2)(3)PPh(2)-MeOH/Me(2)CO-H-2 for copolymerization of ethylene and carbon monoxide

The catalytic system Pd(CF3COO)(2)-Ph(2)P(CH2)(3)PPh(2)-MeOH/Me(2)CO was studied by electrospray mass spectrometry. The {[Pd(dppp)(2)](2+), [(dppp)(2)Pd(CF3COO)](+), [(dppp)Pd(CF3COO)](+), and [(dppp)Pd(CF3COO)(2)Pd(dppp)](2+)} cations were found in the system. The addition of H2O to the system resulted in the formation of binuclear bicharged ions [(dppp)Pd(OH)](2+)(2) and their associates with water.
