sequential borylation and aerobic oxidative copper catalysis, and the corresponding aryl halides, sulfones, azides and arylamines were obtained in good yields. The protocol uses cheap and readily available boron tribromide (BBr3) as the borylating reagent, and inorganic salts (potassium iodide, ammonium bromide, sodium alkylsulfinates, sodium azide) as the functional group sources. This method makes
通过顺序硼化和需氧氧化铜催化,已开发了2-芳基吡啶中芳基CH键的选择性官能化,并以良好的收率获得了相应的芳基卤化物,砜,叠氮化物和芳基胺。该协议使用便宜且容易获得的三溴化硼(BBr 3)作为硼化试剂,并使用无机盐(碘化钾,溴化铵,烷基亚磺酸钠,叠氮化钠)作为官能团来源。该方法使芳基CH键的官能化变得容易。
