The Chemical Nature of 2,4,6-Trichlorobenzoyl Chloride

2,4,6-Trichlorobenzoyl Chloride (CAS 4136-95-2) is an aromatic acyl chloride. Its structure features a benzoyl chloride core with three electron-withdrawing chlorine atoms positioned at the ortho (2, 6) and para (4) positions relative to the acyl chloride group. This substitution pattern significantly influences its reactivity. The compound appears as a pale yellow to colorless transparent liquid and is typically supplied with a purity of ≥97% GC, ensuring high performance in demanding synthesis applications.

Key Reactions and Applications

The primary reactivity of 2,4,6-Trichlorobenzoyl Chloride stems from the electrophilic nature of the carbonyl carbon in the acyl chloride group. This makes it an excellent acylating agent, readily reacting with nucleophiles such as alcohols, amines, and thiols to form esters, amides, and thioesters, respectively. The presence of the chlorine atoms modifies the reactivity and can also impart specific characteristics to the resulting products:

  • Acylation Reactions: Its most common use is in acylating various functional groups. For example, reaction with an alcohol yields an ester, while reaction with an amine forms an amide. These reactions are fundamental in building larger, more complex organic molecules.
  • Friedel-Crafts Acylation: It can participate in Friedel-Crafts acylation reactions with aromatic compounds in the presence of a Lewis acid catalyst, introducing the 2,4,6-trichlorobenzoyl group onto another aromatic ring.
  • Pharmaceutical and Agrochemical Intermediates: The compounds synthesized using 2,4,6-Trichlorobenzoyl Chloride are often vital intermediates for pharmaceuticals, agrochemicals, and specialty materials. The specific arrangement of chlorine atoms can confer desired biological activity or chemical stability.
