Pre-activation of Mn powers by trimethylsilylchloride (TMSCl) enables a highly efficient Ni-catalyzed reductive homocoupling of (hetero)aryl/vinyl chlorides in DMA at room temperature to afford symmetrical biaryls/dienes in good to excellent yields although TMSCl plays a double-face role, activating Mn but deactivating Ni catalyst.

由硅烷基氯化物活化的 Mn 粉末实现的室温镍催化的（杂）芳基/氯乙烯 Ullmann 反应

三甲基硅烷基氯化物（TMSCl）对 Mn 冤的能力的预活化能够在室温下实现 DMA 中（杂）芳基/乙烯基的高效 Ni 催化还原均偶联，从而以良好到优异的产率获得对称的联芳基/二烯烃，尽管 TMSCl 起着双面作用，活化 Mn 但使 Ni 催化剂失活。
