Iron Pincer Complex Catalyzed, Environmentally Benign, <i>E</i>‐Selective Semi‐Hydrogenation of Alkynes

Abstract

Ironing out hydrogenation: For the first time, an iron catalyst provided chemo- and stereo-selective semi-hydrogenation of alkynes to E-alkenes. This efficient, atom-economical reaction is catalyzed by a novel acridine-based PNP iron pincer catalyst and exhibits excellent functional group tolerance under mild, neutral, environmentally benign reaction conditions.
