Acceptorless dehydrogenation (AD) reaction of alcohols are excellent atom-economical approach to yield carbonyl compounds without stoichiometric oxidants. Furthermore the liberated hydrogen can also be used in situ for hydrogenation of the unsaturated intermediates generated by the condensation reaction. Although the aforementioned reactions are based on precious novel-metal catalysts, nowadays several efficient catalysts composed of earth-abundant base metals (Mn, Fe, Co, Ni) have been developed. This review focuses on recent reports about manganese catalyzed C-N bond formation in combination with amines and methanol as a C1 source.
