Abstract: The homogeneous hydrogenation of organic carbonyls, especially esters, under relatively mild conditions using iron hydrido-borohydride catalyst complexes having amino-phosphine pincer ligands. The catalyst and process are well-suited for catalyzing the hydrogenation of a wide variety of organic carbonyls, such as hydrogenation of fatty acid esters to alcohols. In particular embodiments, the process can be carried out in the absence of solvent.
