Copper-catalyzed pentafluoroethylation of aryl/alkenyl iodides with pentafluoroethylsilane†
Abstract
A copper-catalyzed pentafluoroethylation of aryl/alkenyl iodides is described using Et3SiCF2CF3 as a direct CF2CF3 source. An intriguing selective photocatalytic hydrodefluorination of pentafluoroethylarenes is also discovered.
