Title (EN) IRON-CATALYZED TRANSFER HYDROGENATION OF ESTERS TO ALCOHOLS
(FR) HYDROGÉNATION PAR TRANSFERT CATALYSÉE PAR DU FER D'ESTERS EN ALCOOLS
Abstract:
(EN) Iron-based homogeneous catalysts, supported by pincer ligands, are employed in the transfer hydrogenation of esters using C2-C12 alcohols as sacrificial hydrogen donors to produce corresponding alcohols from the esters. No external H2 pressure is required. The reaction can be carried out under ambient pressure.
(FR) La présente invention concerne des catalyseurs homogènes à base de fer, supportés par des ligands pinces, qui sont utilisés dans l'hydrogénation par transfert d'esters à l'aide d'alcools C2-C12 en tant que donneurs d'hydrogène sacrificiels pour produire des alcools correspondants à partir d'esters. Aucune pression H2 externe n'est nécessaire. La réaction peut être effectuée sous pression ambiante.
