Reactions of Zr(OPrn)(4) and Zr(OBun)(4) with 3-pentenoic acid (PA) in 1:1 molar ratio were studied in propanol and butanol solution at room temperature by the sol-gel process. The complexations were investigated by C-13{H-1}, H-1-NMR and FTIR spectroscopy. The C-13{H-1}, H-1-NMR and FTIR spectra showed that PA completely reacted with Zr(OPrn)(4) and Zr(OBun)(4). The new products were hydrolyzed by water in a ratio of 1:4 (Zr(ORn)(4)/H2O, R = propyl, butyl). The stability of hydrolyzed products was investigated spectroscopically. After hydrolysis, it was observed that no PA was released from the complexes, [Zr(OPrn)(3)(PA)] and [Zr(OBun)(3)(PA)], under the reaction conditions.
