| Abstract: The six complexes, (RC5H4)2Ti(O2CR')2(I, R = H, R' = β-NHPhC6H4; E, R = CH3, R' = o-NHPhC6H4; Ⅲ, R = CH3, R'=α-C10H7; IV, R = CH3, R' = β-C10H7; V, R = CH3, R' = α-C10H7CH2; VI, R = CH3, R' = 2-PhC9H5N-4-), have been prepared and characterized by elemental analysis, IR, 1H-NMR and 13C-NMR. IR data show the carboxylates in the complexes coordinate to Ti atom in monodentate bonding. The catalytic hydrogenation of hcxcne-1 by complex (I)-NaH in normal condition has been shown the high initial catalytic activity and high catalytic efficiency. |
