2,4,6-Trichlorobenzoyl chloride or Yamaguchi's reagent is an chlorinated aromatic compound that is commonly used in a variety of organic syntheses.
[2][3] It is the primary reactant in Yamaguchi esterification.
2,4,6-Trichlorobenzoyl chloride is prepared by reacting 2,4,6-trichloroaniline with n-butyllithium in a carbon dioxide atmosphere.
[4] Since 2,4,6-trichlorobenzoic acid is produced as a by product of the Yamaguchi esterification process, it can be refluxed again to recreate 2,4,6-trichlorobenzoyl chloride.
