title: Regio- and Stereoselective Cyanotriflation of Alkynes Using Aryl(cyano)iodonium Triflates.
abstract: A novel, mild, and versatile approach for regioselective syn-addition of both the CN and OTf groups of aryl(cyano)iodonium triflates to alkynes is described. The reaction uses Fe-catalysis and can be conducted in gram scale. Products of the vicinal cyanotriflation can be stereospecifically readily further functionalized, rendering the method highly valuable.
