Synthesis method of triphenylphosphine derivative tri-(R-phenyl) phosphine
The invention relates to a synthesis method of a triphenylphosphine derivative tri-(R-phenyl) phosphine. The synthesis method comprises the following steps: adding magnesium chips, a solvent and R-substituted halobenzene into a reaction kettle under the protection of nitrogen, initiating a reaction at a proper temperature, and dropwise adding an R-substituted halobenzene solution to synthesize anintermediate; dropwise adding a phosphorus trichloride solution to complete a Grignard reaction; dropwise adding diluted hydrochloric acid for hydrolysis after negative-pressure desolvation; and carrying out post-treatment to obtain TRPP. According to the method, the tri-(R-phenyl) phosphine of which the purity is greater than 99% is obtained with high selectivity and high yield.
