The study on homogeneous hydrogen transfer from indoline, 2-propanol, and L- (+) -ascorbic acid to methyl linoleate was made. Metal complexes, RuH2 (PPh3) 4, RuCl2 (PPh3) 3, RhH (PPh3) 4, and RhCl3·2H2O were used as homogeneous catalysts. Even under mild conditions, the hydrogenation of the diene proceeded easily. In the hydrogen transfer from L- (+) -ascorbic acid catalyzed by any catalyst shown above, and that from 2-propanol catalyzed by RuCl2 (PPh3) 3 or RhCl3·2H2O, the reduction of linoleate was selective and no stearate was produced. In the cases of the hydrogenation with 2-propanol and L- (+) -ascorbic acid, the formation of isolated trans double bonds was insignificant.
