Selective and efficient: The copper(II)‐catalyzed selective monoarylation of vicinal diols with diaryliodonium triflates was successfully developed. In this catalytic process high chemoselectivity was achieved, even in the presence of a 1:1 mixture of the 1,2‐diol and the mono‐ol, and a wide range of substrates was tolerated, giving the monoarylated products in good to excellent yields (see scheme)
选择性和高效:成功开发了铜(II)催化邻二元二醇与二芳基碘鎓三氟甲磺酸酯的选择性单芳基化反应。在这种催化过程中,即使存在1,2-二醇和一元醇的1:1混合物,也能实现高化学选择性,并且可以耐受多种底物,从而使单芳基化产物的收率良好至优异(请参阅方案)。
