Abstract

Catalytic transfer hydrogenation is a mild and effective way of reducing carbonyl functionalities that involves alcohols or ammonium formate as hydrogen donors and RuII, IrI, or RhI complexes as catalysts.[1, 2] Transfer hydrogenation of ketones and imines is well known since these polar double bonds are easily reduced to the corresponding alcohols and amines,[3–5] whereas transfer hydrogenation of non-polarized carbon–carbon ...
