The direct synthesis of diaryl sulfones from aryl silanes, SO2 surrogate, and aryl iodides is performed thanks to an air-stable Cu(I)-catalyzed sulfonylative Hiyama cross-coupling. Experimental and theoretical studies support a Cu(I)/Cu(III)-based mechanism with fast insertion of the small molecule into the Cu−C bond of a copper-aryl intermediate.
由于空气稳定的 Cu(I) 催化的磺酰化 Hiyama 交叉偶联,可以从芳基硅烷、SO 2替代物和芳基碘化物直接合成二芳基砜。实验和理论研究支持基于 Cu(I)/Cu(III) 的机制,即小分子快速插入到铜-芳基中间体的 Cu-C 键中。
