Radical Fluoroalkylation of Isocyanides with Fluorinated Sulfones by Visible-Light Photoredox Catalysis

摘要

The radical fluoroalkylation of isocyanides with fluorinated sulfones is enabled by visible-light photoredox catalysis. A wide range of readily available mono-, di-, and trifluoromethyl heteroaryl sulfones can thus be used as efficient radical fluoroalkylation reagents under mild conditions. This method not only describes a new synthetic application of fluorinated sulfones, but also provides a new route to fluoroalkyl radicals.
