The complex Pd(PPh3)2Cl2*CCl4 has been prepared by treatment of Pd(OAc)2 with PPh3 in CCl4. 1H NMR, 31P NMR, data are given. The molecular structure of Pd(PPh3)2Cl2 has been determined by single crystal X-rays diffraction. The reaction mechanism is tentatively proposed and discussed. Radicals were trapped by PBN. This reaction was proved to be a free radical reaction by EPR-ST method. The solvent CCl4 participated in the reaction.
