Abstract: Complex PdCl2[(PPh2)2CHCl] has been prepared by treatment of Pd(OAc)2 with dppm in solvent CH2Cl2. IR,1H NMR, 31P NMR, elemental analysis, EDS data are given. The molecular structure of PdCl2[(PPh2)CHCl] has been determined by single crystal X-ray diffeaction. The reaction mechanism is tentatively proposed and discussed. Radicals.PPh2 and other radicals were trapped by PBN. This reaction was proved to be a free radical reaction by EPR-ST method. The solvent CH2Cl2 participated in the reaction.

Key words: EPR-ST, Pd complex, Free radical mechanism
