摘要

在这里，我们描述了一个近红外到蓝色的三重态-三重态湮灭上转换系统，产生高度氧化激发态。锇敏化剂的自旋禁止激发和热辅助三重态能量向蒽湮灭体的转移使反斯托克斯位移达到1.25 V。然后将该系统应用于镍/光氧化还原催化芳基卤化物和醇的双交叉偶联。最后，我们暗示上转化作为还原消除镍（II）芳基烷氧化物络合物的启动子。

Dual Nickel/Photoredox-Catalyzed Aryl Etherification Enabled by an Oxidative Near-Infrared-to-Blue Triplet–Triplet Annihilation Upconversion System Leveraging Spin-Forbidden Excitation

Herein we describe a near-infrared-to-blue triplet–triplet annihilation upconversion system that produces a highly oxidizing excited state. The spin-forbidden excitation of the osmium sensitizer and thermally assisted triplet energy transfer to the anthracene annihilator enable an anti-Stokes shift of 1.25 V. This system is then applied to the dual nickel/photoredox-catalyzed cross-coupling of aryl halides and alcohols. Finally, we implicate upconversion as the promoter for reductive elimination of a nickel(II) aryl alkoxide complex.
