To provide a method for safely and inexpensively producing an acid halide having a leaving group and a bulky group with high accuracy in selectiveness.
The production method of the acid halide includes a process for obtaining a carboxylic acid derivative by making a compound expressed by a general formula (III), a basic compound and a compound expressed by a general formula (IV) react with one another, and a process for obtaining a compound expressed by a general formula (I) by making the carboxylic acid derivative react with an acid halide agent. In the general formula (I), R1 and R2 are each independently a group selected from groups composed of alkyl, allyl, alkenyl, alkynyl, and hetero ring. R3 denotes an alkylene group. X1denotes a halogen atom. L1 denotes a leaving group. In the general formula (III), R1 and R2 are synonymous with R1 and R2 in the general formula (I), respectively. M denotes a hydrogen atom or a metal atom. In the general formula (IV), R3 and L1 are synonymous with R3 and L1 in the general formula (I), respectively. L2 denotes the leaving group.
