A method for preparing dimethyl zinc, comprising the steps of: adding zinc chloride to a reaction kettle under nitrogen protection, and then adding the moles of trimethylaluminum, trimethylaluminum and zinc chloride dropwise under stirring conditions. The ratio is 1: 1.8. The reaction speed is controlled by the dropping acceleration of trimethylaluminum. After the completion of the dropping of trimethylaluminum, the stirring reaction is continued for 4.5 hours, and then the temperature of the kettle is adjusted to 42 ° C and maintained for 2h. The distilled Zn is collected (CH3) 2; Then, diethyl zinc was added dropwise to the reaction kettle, and the molar ratio of trimethylaluminum and diethyl zinc was 1.3: 1, and the temperature of the reaction kettle was controlled to 91 ° C. The distilled Zn ( CH3) 2. After the addition of diethylzinc was completed, the temperature of the kettle was maintained at 91 ° C, and Zn (CH3) 2 was collected for 3 hours.The yield of dimethylzinc in this example is 92% (calculated as the methyl group of trimethylaluminum).
