在1- 3mol%SIPr-连接的Pd（OAc）_2和0.6当量对苯醌存在下，各种芳基硼酸在室温下在MeOH中发生自偶联，以38-96%的产率生成对称的联芳基化合物。
In the presence of 1-3 mol% SIPr-ligated Pd(OAc) 2 and 0.6 equivalent of P-benzoquinone, various arylboronic acids underwent homocoupling in MeOH at ambient temperature to produce symmetrical biaryls in 38-96% yields.
