A clean sweep : Aryl and aliphatic imines can be synthesized directly and efficiently from alcohols and amines under mild, neutral conditions with the liberation of only molecular hydrogen and water (see scheme; R=isopropyl, tert ‐butyl). This general, environmentally benign reaction is catalyzed by a de‐aromatized ruthenium PNP pincer complex (0.2 mol %), and can proceed in toluene under an inert atmosphere or under air.
