A nickel-catalyzed reductive coupling of aryl triflates with thiocarbonates is reported here. Both electron-rich and -deficient aryl C(sp2)–O electrophiles as well as a class of O-tBu S-alkyl thiocarbonates are compatible with the optimized reaction conditions, as evidenced by 49 examples. The reaction also proceeds with good chemoselective cleavage of the C–O bond with regard to thioesters. This work
此处报道了芳基三氟甲磺酸酯与硫代碳酸酯的镍催化还原偶联。富电子和不足的芳基C(sp 2)-O亲电体以及一类O - t Bu S-烷基硫代碳酸酯都与优化的反应条件兼容,如49个实例所示。对于硫代酯,该反应还会以良好的C–O键化学选择性裂解来进行。这项工作拓宽了镍催化的还原交叉亲电子偶联反应的范围。
