An N-formylation method using methanol as the C1 source without a stoichiometric amount of activating reagent is described. Nitriles as well as amines can be directly used as substrates. The reaction is catalyzed by an N-heterocyclic carbene coordinated ruthenium(II) dihydride complex, which mediates methanol dehydrogenation, nitrile reduction, and C-N bond formation without any external base, hydrogen acceptor, or oxidant. © 2015 WILEY-VCH Verlag GmbH & Co.

Oxidation of alcohols is an essential organic reaction, affording versatile carbonyl groups. To provide a sustainable solution for environmentally harmful traditional oxidation methods, the transition-metal catalyzed acceptor-free dehydrogenation of alcohols has attracted much attention. The widely used catalysts for the dehydrogenation reaction are based on precious metals, which are not economical and environmentally benign. We developed an operationally simple, economical, and environmentally benign acceptorless Fe-catalyzed dehydrogenation of various secondary benzylic alcohols to afford the corresponding ketones and H2. A simple in situ mixture of readily available Fe(III) acetylacetonate, 1,10-phenanthroline, and K2CO3 was identified as an active catalyst for this transformation. © 2014 American Chemical Society.
