Abstract
DFT calculations have been performed to gain mechanistic insight into ester hydrogenation to alcohols (exemplified by PhCO2CH3+ 2H2→ PhCH2OH+ CH3OH), catalyzed by a well- defined Fe-PNP pincer hydridoborohydride complex (1). The entire catalytic process includes precatalyst activation to an active species trans-dihydride complex 2, 2-catalyzed transformation of PhCO2CH3+ H2→ PhCHO+ CH3OH, hydrogenation of PhCHO to ...
