Abstract:

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.

Key words: Pd(OAc)2, EPR-ST, Complex PdCl2(PPh3)2?CCl 4, Free radical mechanism
