Synthesis method of 2, 2-dimethyl butyryl chloride

The invention relates to the technical field of organic synthesis, and provides a synthesis method of 2, 2-dimethyl butyryl chloride, which comprises the following steps: by taking 2, 2-dimethyl butyric acid as a reaction raw material, carrying out chloroacylation reaction under the action of a chlorination reagent to obtain 2, 2-dimethyl butyryl chloride; the chlorination reagent comprises bis (trichloromethyl) carbonate and oxalyl chloride. Through the technical scheme, the problems of low yield and low purity of 2, 2-dimethylbutyryl chloride in the prior art are solved. 本发明涉及有机合成技术领域，提出了一种2,2-二甲基丁酰氯的合成方法，以2,2-二甲基丁酸作为反应原料，在氯化试剂的作用下，进行氯酰化反应，得到2,2-二甲基丁酰氯；所述氯化试剂包括二(三氯甲基)碳酸酯和草酰氯。通过上述技术方案，解决了现有技术中的2,2-二甲基丁酰氯收率低和纯度低的问题。
