Abstract

A process for the deoxygenation of organic oxo compounds, in particular phosphine oxides to phosphines and nitrobenzene to aniline, with reduced redox catalysts in a non-steady-state reaction with decoupled reductive regeneration of the redox catalyst entails the redox catalyst being reduced to a lower oxidation state and being reused for the deoxygenation.
