Diaryl ketones are of much importance in organic synthesis as versatile intermediates and in industry for their useful properties. A mild and efficient palladium-catalyzed traditional ligand-free decarboxylative coupling of aryl α-keto carboxylic acid with aryl diazonium fluoroborate has been developed. A series of unsymmetrical diaryl ketones has been synthesized in moderate to good yields using this procedure. A radical pathway involving the acyl radical has been suggested.

α-氧代羧酸与芳基重氮四氟硼酸酯的钯催化无配体脱羧偶联：获得不对称的二芳基酮
二芳基酮作为有用的中间体在有机合成中和工业上都非常重要。已开发出温和而有效的芳族α-酮基羧酸与芳基重氮氟硼酸酯的钯催化传统的无配体脱羧偶联反应。使用该方法已以中等至良好的产率合成了一系列不对称的二芳基酮。已经提出了涉及酰基自由基的自由基途径。
