Abstract
AbstractWe herein describe an efficient iron‐catalyzed selective N‐methylation and N‐formylation of amines with CO2 and silane using mono‐phosphine as ligand. With commercially available [CpFe(CO)2]2 as catalyst, Fe‐catalyzed methylation of amines was achieved with triphenylphosphine as a ligand. Using tributylphosphine as a ligand, Fe‐catalyzed formylation of amines was realized at a lower temperature. The method was successfully applied in the late‐stage methylation and formylation of drug molecules containing amine moiety.magnified image
