Abstract

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 and cheap. This method can be easily adapted for large-scale preparation.
