A method of preparing a palladium complex thereof
2008
The present invention provides a method for preparing a palladium complex, for the preparation process: PdCl2 inorganic palladium salt dissolved in an organic solvent to obtain a solution A, the solution B obtained dppf in a solvent, the solution is added to the A B after the solution or the B solution was added to the solution A, stirring continuously, the reaction was filtered 1.5-5 hours, to give red-orange crystals Pd (dppf) Cl2, where, Pd is a divalent palladium ion, dppf 1,1 - bis (diphenylphosphino) ferrocene; the organic solvent is ethanol a tetrahydrofuran or toluene or a mixed solvent of two or more. The present invention is simple, synthetic materials, low in cost, product prepared precipitated in crystalline form, large purity, high yield; and palladium complexes prepared in the present invention can stably exist in the natural state, in the carbonylation reaction, the cross coupling reaction, Suzuki reaction exhibit excellent catalytic effect.
