A catalytic system for the atom‐economical Ru‐catalyzed reductive amidation of aldehydes was developed. A cyclopentadienyl ruthenium catalyst was employed in this process with loadings as low as 0.5–1 mol‐%, and carbon monoxide was used as the deoxygenative agent. A number amides and aromatic aldehydes were able to successfully afford the corresponding secondary amide in yields of 79–84 %.

using rhodium on carbon matrix as catalyst was developed. The method does not require any external hydrogen source and carbon monoxide is used as a reducing agent. The most active rhodium catalysts were characterized by BET, TEM and XPS techniques. Unexpectedly, it was found that heterogeneous rhodium on carbon matrix works as precatalyst for homogenous active species due to leaching of rhodium to the
