| titleOfInvention | A kind of preparation method of chlorine (crotyl) (3-tert-butylphosphorus) palladium (II) |
| abstract | The invention discloses a preparation method of chloro(crotyl) (3-tert-butylphosphorus) palladium (II), comprising the following steps: step 1, in a nitrogen atmosphere, dropwise adding crotyl chloride to an aqueous palladium chloride solution Then, the reaction is stirred at a temperature of 20°C to 50°C; in step 2, the post-reaction system is extracted with an extractant, liquid-separated, dried, and concentrated to obtain a crotyl palladium chloride dimer; step 3, at 30°C to 50°C Under the temperature condition of 50 ℃, the organic solvent, tri-tert-butylphosphine and crotyl palladium chloride dimer are mixed and stirred for 7h～15h, filtered, washed, and dried in vacuo to obtain chloro(crotyl)(3-tert-butylene) base phosphorus) palladium (II). The invention provides a method for preparing chloro(crotyl)(3-tert-butylphosphorus)palladium(II), which is simple and easy to implement, environmentally friendly, and has high yield. The prepared chloro(crotyl)(3- The purity of tert-butylphosphorus) palladium (II) is greater than or equal to 99%, and the yield is greater than 91%. |
