Selective N -formylation/ N -methylation of amines and N -formylation of amides and carbamates with carbon dioxide and hydrosilanes: promotion of the basic counter anions of the zinc catalyst

A Zn(OAc) ₂ catalyst bearing the 1,10-phenanthroline (phen) ligand was efficient in the N -formylation of organic amine derivatives ( e.g. , amines, amides, and carbamates) using carbon dioxide (CO ₂ ) and hydrosilanes.
