| Abstract: | The complex Pd(PPh-3)-2Cl-25CCl-4 has been prepared by treatment of Pd(OAc)-2 with PPh-3 in CCl-4. {}+1H NMR, {}+{31}P NMR, data are given. The molecular structure of Pd(PPh-3)-2Cl-2 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 CCl-4 participated in the reaction. |
