| Abstract: | Complex PdCl2 (PPh2 )2CHCl] has been prepared by treatment of Pd(OAc)2 with dppm in solvent CHaCla. IR,1 H 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. |
