The invention discloses a synthetic method of 3,5-dihalogenated-2-pentanone, and belongs to the technical field of organic chemistry. According to the method, acetoacetate is taken as a raw material,and cyclopropanation, ring-opening halogenation and hydrolysis decarboxylation reactions are carried out successively so as to obtain 3,5-dihalogenated-2-pentanone. The method has the advantages of simple and accessible raw materials, high atom utilization ratio in the halogenation step and fewer wastes. The reaction conditions of all steps are simple, purification is not needed in the process, continuous feeding can be achieved, cyclic application of the cyclopropanation catalyst can be achieved, and potential industrial amplification prospects are achieved.
