The Uses of 3,5-Dichlorobenzoyl chloride
3,5-Dichlorobenzoyl chloride is a useful intermediate for organic synthesis and other pharmaceutical processes.
The Uses of 3,5-Dichlorobenzoyl chloride
3,5-Dichlorobenzoyl chloride has been used in the preparation of:
- N-(1,1-dimethylpropynyl)-3,5-dichlorobenzamide, herbicide
- (3,5-dichlorophenyl)(2-(4-methoxyphenyl)-5-methylbenzofuran-3-yl)methanone

Non flammable
Synthesis
3,5-Dichlorobenzoyl chloride is obtained by reacting by aryl carboxylic acid with DMF.Dissolve aryl carboxylic acid (10.0 mmol) in 50 mL DCM with drops of DMF
to a 100 mL roundbottomed flask. Cool the mixture to 0°C. Add oxalyl
chloride (20.0 mmol, 2.0 equivalents) dropwise to the reaction mixture.
Allow the reaction mixture to react for another 4 hours. Concentrate the
solvent in vacuo. Use the remaining residue directly.
