  An Efficient Preparation of β-Aryl-β-ketophosphonates by the TFAA/H₃PO₄-Mediated Acylation of Arenes with Phosphonoacetic Acids

  摘要：

  [GRAPHICS]beta-Aryl-beta-ketophosphonates can be efficiently prepared in good yield by using a TFAA/85% H(3)PO(4)-mediated acylation of electron-rich arenes with phosphonoacetic acids. The conditions offer advantages over existing methods of preparing these useful compounds by not requiring the use of strong base, cryogenics, or an anhydrous and inert atmosphere. Furthermore, some functional groups not tolerated with the reaction conditions used in existing methods are compatible with the herein described conditions.
