Through the comparision of carbon tetrachloride method, phosgene method, carbon monoxide method, oxidation method and others in the production of diaryl ketone compound, advantages and disadvantages of the above mentioned methods are briefly introduced.

Three synthetic methods of biaryl ketones,from a-diarylcarboxylic acid,oxidation of diarylacetonitrile,the catalyzed couplings of aldehyde or carboxylic derivatives with Organoboride Reagents,are reviewed.

Synthesis of diarylketones catalyzed by fecl_3-doped bentonite under microwave irradiation;

The mixed solvent of ionic liquid 1-butyl-3-methylimidazolium tetrafluoroborate and water has efficiently promoted the synthesis of a variety of 5-arylmethylidene-4-oxo-2-thiothiazolidines from the cor- responding aromatic aldehydes and rhodanine at room temperature in 80%～93% yields within 10 to 120 min.
