说明

一般描述

Chloroform, a halogenated hydrocarbon, is widely used as a solvent and extractant in various manufacturing and laboratory procedures. It can be produced by the chlorination of methane or lower-chlorinated methanes. Additionally, it is employed in the production of dichlorocarbenes, α-trichloromethyl carbinols, and trichlorolithiocarbenoids.
 

应用

Chloroform can be used as a solvent in the:
  • Enzyme-catalyzed ring-opening polymerization of ω-pentadecalactone to prepare polyesters.
  • Pd-catalyzed cross-coupling reaction of acid chlorides with arylboronic acids to synthesize diaryl Ketones.
  • Enantio- and diastereoselective nitro-Mannich reaction of α-aryl nitromethanes with amido sulfones to synthesize β-nitroamines.
  • Diels-Alder reaction to synthesize spiro-fused dihydropyans. The hydrogen bond (CH-O) formed between chloroform and carbonyl oxygen makes the carbonyl group a stronger heterodienophile, resulting in an increased reaction rate.
