Abstract

The invention provides a preparation method of palladium coordination compound, which comprises the following steps: dissolving inorganic palladium salt PdCl2 in an organic solvent to obtain an A solution; dissolving dppf in a solvent to obtain a B solution; adding the A solution into the B solution or adding the B solution into the A solution, stirring continuously, and filtering after reacting for 1.5-5 hours to obtain a salmon pink crystal Pd(dppf)Cl2; wherein Pd is bivalence palladium ion, dppf is 1,1-bi(diphenylphosphine)dicyclopentadienyl iron, the organic solvent is one or mixing solution of two of anhydrousl alcohol, tetrahydrofuran and toluol. The invention has the advantages of simple operation, easily-obtained raw materials and low cost, and the obtained product is separated out in form of crystal and has high purity and yield rate. In addition, the palladium coordination compound prepared in the invention can stably exist in the natural condition and plays a role of catalyzation in carbonylation reaction, cross-coupling reaction and suzuki coupling reaction.

Description

technical field [0001] The invention relates to a preparation method of a metal complex, in particular to a preparation method of a palladium complex. Background technique [0002] Among all the transition metals, palladium is the most widely used in organic synthesis. The organic palladium complexes can accept many different kinds of functional groups, and can promote various reactions that generate C-C bonds and other bonds, and these reactions often have high chemoselectivity and regioselectivity. Various phosphine bridge transition dinuclear complexes based on bidentate phosphine ligands have attracted widespread attention due to their special structure, novel reaction performance and catalytic behavior, and have become a frontier field of metal organic chemistry,1,1 -Bis(diphenylphosphino)ferrocene can be used as a potentially useful bidentate phosphine ligand, and can form various bimetallic and multimetallic complexes with another transition metal atom. When 1,1-bis...
