  of Csp3-bromides. Specifically, a copper/photoredox dual catalytic system for the coupling of alkyl bromides with trifluoromethyl groups is presented. This operationally simple and robust protocol successfully converts a variety of alkyl, allyl, benzyl, and heterobenzyl bromides into the corresponding alkyl trifluoromethanes.

  铜氧化加成到有机卤化物中是一个具有挑战性的双电子过程。相比之下，铜与 Csp2 碳-溴键的正式氧化加成可以通过在光氧化还原条件下使用潜在的甲硅烷基自由基来完成。这种铜氧化加成的新范例现已应用于铜催化的 Csp3-溴化物交叉偶联。具体而言，提出了一种用于烷基溴与三氟甲基偶联的铜/光氧化还原双催化系统。这种操作简单且可靠的方案成功地将各种烷基、烯丙基、苄基和杂苄基溴化物转化为相应的烷基三氟甲烷。
