General description

Acetyl chloride undergoes reaction with decalin and aluminum trichloride to afford a tricyclic enol ether. It promotes the cyclopropanation of alkene with dibromomethane or diiodomethane in the presence of Zn dust and copper chloride in ether. Friedel-Crafts reaction of acetyl chloride with benzene in the presence of MCl3 (M = Al or Fe) in the ionic liquid 1-butyl-3-methylimidazolium chloride affords MCl3 adducts of the acetyl chloride, the acetylium ion [CH3CO]+[MCl4]- and the MCl3 adduct of acetophenone.

Application

  • Synthesis, Characterization, and Evaluation of Thiazolidine Derivatives of Cysteine for Suppressing Eumelanin Production.: The study discusses the synthesis and evaluation of thiazolidine derivatives of cysteine, where acetyl chloride is used as a reagent, underscoring its importance in pharmaceutical intermediate development. (Amino et al., 2016).
  • New URJC-1 Material with Remarkable Stability and Acid-Base Catalytic Properties.: This research introduces the new URJC-1 material, noting its stability and catalytic properties, with acetyl chloride being pivotal in the synthesis process, illustrating its role in material science and catalysis. (Leo et al., 2016).
