Disclosed are a 3-N-cyclopropylmethyl-2-fluorobenzamide compound, a preparation method therefor and the use thereof. The compound has a structure as represented by the following formula I. This compound can be used for the preparation of an m-diamide compound substituted with a 3-N-cyclopropylmethyl derivative. The m-diamide compound substituted with the 3-N-cyclopropylmethyl derivative, when serving as an insecticide, has the characteristics of a good fast-acting property, needing to use a low amount thereof, and being more beneficial for environmental protection. The 3-N-cyclopropylmethyl-2-fluorobenzamide compound is easy to synthesize and has mild conditions, and when used for preparing a m-diamide compound insecticide substituted with a 3-N-cyclopropylmethyl derivative, same is easy to synthesize and has a low synthesis cost and a high yield. |
