A new and general method for the synthesis of β-azidosulfonates has been achieved through Cu(I)-mediated radical oxidative sulfonylation–azidation of alkenes with sodium sulfinates. Under identical conditions, azido fluoroalkyated products could be readily obtained instead using CF3SO2Na or CHF2SO2Na as reagents. The starting materials of sulfinate compounds, alkenes, and azidotrimethylsilane are stable
通过Cu(I)介导的自由基与亚磺酸钠的烯烃氧化合磺化反应,已经获得了一种合成β-叠氮基磺酸盐的新的通用方法。在相同条件下,使用CF 3 SO 2 Na或CHF 2 SO 2 Na作为试剂,可以轻松获得叠氮基氟代烷基化产物。亚磺酸盐化合物,烯烃和叠氮基三甲基硅烷的起始原料是稳定且便宜的。该方法可以轻松地用于大规模制备。
