Photoredox/nickel dual catalysis via single electron transmetalation allows coupling of Csp3–Csp2 hybridized centers under mild conditions. A procedure for the coupling of electron-deficient aryl triflates, -tosylates, and -mesylates with alkylbis(catecholato)silicates is presented. This method represents the first example of the use of phenol derivatives as electrophilic coupling partners in photoredox/nickel
通过单电子金属转移作用的光氧化还原/镍双重催化可在温和条件下偶联C sp 3 –C sp 2杂化中心。提出了将缺电子的芳基三氟甲磺酸酯,-甲苯磺酸酯和-甲磺酸酯与烷基双(邻苯二酚)硅酸酯偶联的方法。该方法代表了在光氧化还原/镍双重催化中使用苯酚衍生物作为亲电偶联伴侣的第一个例子。
