Summary:The invention discloses a synthesis method of methoxyfenozide key intermediate-substituted methyl benzoyl chloride. The corresponding substituted methyl benzoyl chloride is obtained by reacting 3,5-mesitylenic acid or 3-methoxyl-2-methyl benzoic acid with di(trichloromethyl)carbonic ester under the action of an organic amine catalyst in an organic solvent according to a chemical equation. The method has the advantages of mild reaction condition, safe and reliable operating process, high product yield, elimination of potential safety hazard from a process source, reduction in three waste generating sources, and high industrial implementation value.
