ABSTRACT
Federica.Zaccheria@unimi.it Abstract Several low loading supported copper catalysts were tested in the hydrogen transfer reduction of 4-tert-butyl-cyclohexanone showing good activity under very mild conditions (2-propanol as solvent, 83°C, N2). Results obtained by using different alcohols as donors suggest that a two step dehydrogenationhydrogenation mechanism is operating over Cu/SiO2. Introduction Catalyzed hydrogen transfer from a hydrogen donor other than H2 is attractive industrially because of safety, engineering and economic concerns (1). This reaction has been extensively studied in the homogeneous phase (2) and under Meerwein-Ponndorf-Verley conditions (3).
