Rhodium-Catalyzed Direct C‑H Bond Cyanation in Ionic Liquids

A Cp*Rh­(III)/IL-based direct C-H bond cyanation system was developed for the first time. The system is a mild, efficient, and recyclable method for the synthesis of aryl nitriles. Many different directing groups can be used in this cyanation, and the reaction tolerates a variety of functional groups
