A highlyselectivePd/Cu‐cocatalyzed aerobicoxidativecarbonylativehomocoupling of arylboronicacids has been developed. This method employs a simple catalytic system, readily available boronic acids as the substrates, molecular oxygen as the oxidant, and 1 atm of CO/O2, which makes this method practical for further applications.

of arylhydrazine with CO and molecular oxygen as an oxidant to afford symmetrical biaryl ketones viaC—N bond activation has been developed. In this approach, arylhydrazine hydrochlorides are used as a green arylating agent which releases nitrogen and water as byproducts. This developed protocol significantly restricts the formation of aryl iodide and homo-coupled azobenzene products even under favorable
开发了一种有效的 Pd/Cu 催化芳基肼与 CO 和分子氧作为氧化剂的氧化自羰基化反应,通过 CN 键活化提供对称联芳基酮。在该方法中,使用芳基肼盐酸盐作为绿色芳基化剂,其释放氮和水作为副产物。即使在有利的条件下,该开发的方案也显着限制了芳基碘化物和均偶偶氮苯产物的形成。在温和条件下以良好的产率合成了具有广泛官能度的对称联芳基酮文库。
