Abstract

With 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.
