  空气中室温铜催化的缺电子芳烃和杂芳烃的氧化

  摘要：

  无压力：室温下，芳烃CH键的氧化是通过在空气存在下，铜催化的芳烃和杂芳烃的“加氧酶型”氧化实现的（请参见方案）。该反应涉及氧原子从空气中的O 2转移到基质上。

  日期：2010.3.19

  A number of first-row transition metal salts catalyze deprotonative dimerization of acidic arenes. Under the atmosphere of oxygen, nickel, manganese, cobalt, and Iron chlorides have been shown to dimerize five- and six-membered ring heterocycles as well as electron-poor arenes. Both tetramethylpiperidide and dicyclohexylamide bases can be employed; however, the former afford slightly higher yields.

  A general method for copper-catalyzed deprotonative dimerization of arenes by employing oxygen as the terminal oxidant has been developed. Electron-rich and electron-poor heterocycles as well as electron-poor arenes are reactive. The method is tolerant to functionalities such as nitro, cyano, dialkylamino, and ester groups.
