α-arylation of ketones with aryl halides catalyzed by the easily prepared and air-stable palladium complex (SIPr)-Pd(Py)Cl 2 (3) is described. Complex 3 displays high activity for a variety of aryl halides (activated, unactivated, and sterically hindered aryl halides) under mild conditions. Moreover, both aryl and alkyl ketones can be arylated. The α-arylation of some alkyl ketones can even be run at room
描述了由易于制备且空气稳定的钯配合物 (SIPr)-Pd(Py)Cl 2 (3) 催化的酮与芳基卤化物的 α-芳基化反应。配合物 3 在温和条件下对各种芳基卤化物(活化的、未活化的和空间位阻的芳基卤化物)显示出高活性。此外,芳基酮和烷基酮都可以被芳基化。一些烷基酮的 α-芳基化甚至可以在室温下进行。不受阻二烷基酮3-戊酮的单芳基化或二芳基化产物可以通过温度和酮与芳基卤化物的比例来控制。
