The catalytic synthesis of tetraphenylphosphonium bromide were studied using triphenyl phasphine and phenyl- bromide as starting materials and nickelus chloride as catalyst. The effects of reaction temperature, solvent and reaction time on the product yield were studied. The catalyst's recovey and the product's purification process are also discussed. The reaction was carried out in harmless solvent of n-octanol at 195℃ for 6h with the yield of 89%. The result on product yeild and environmentally friendship has never been reported in present literatures.
