General description

5′-Chloro-2′-hydroxyacetophenone (5-chloro-2- hydroxyacetophenone) on condensation with salicylhydrazide yields Schiff base, which is reported to form copper(II) complexes. Dipole moment of 5-chloro-2- hydroxyacetophenone has been evaluated in benzene solution.

Application

5′-Chloro-2′-hydroxyacetophenone (5-chloro-2- hydroxyacetophenone) may be used in the synthesis of:
  • 6-chloro-2-methyl-4H-chrome-4-one
  • 1-(2-hydroxyphenyl)-5-phenyl-2,4-pentadien-1-ones
  • 1-(2-hydroxyphenyl)-5-phenyl-2,4-pentadien-1-ones
  • 2-styrenyl allyl ether

Due to their physicochemical and toxicological properties, polychlorinated dibenzofurans are regarded as a class of compounds providing reason for serious environmental concern. While the nonhalogenated basic structure dibenzofuran is effectively mineralized by appropriate bacterial strains, its polychlorinated derivatives are not.
