AbstractWith nitromethane and diphenylsilane (Ph2SiH2), zinc triflate behaves as a Lewis acid catalyst for the cyanation of nitrogen‐containing heteroarenes such as indoles and pyrroles. This is the first realization of the Lewis acid‐catalyzed direct cyanation of a C(aryl)H bond with no CN group‐containing cyanating agent.magnified image
