Özet

Tin and titanium pentenoate have been prepared from tin(IV) butoxide and titanium (IV) isopropoxide in alcohol and 3-pentenoic acid. Reactions of Sn(OBun )4 and Ti(OPri )4 with 3-pentenoic acid in 1:1 molar ratio were studied in butanol and propanol solution at room temperature by sol-gel process. The complexations were investigated by 13C, 1 HNMR and FT-IR spectroscopy. 13C{1 H}, 1 H-NMR and FT-IR spectra showed that 3-pentenoic acid completely reacted with Sn(OBun )4 and Ti(OPri )4. These new products were hydrolyzed by water in ratio of 1:4 [M(OR)4 /H2O, M: Sn, Ti, R: butyl and isopropyl ]. The stability of hydrolyzed products was investigated by 13C, 1 H NMR and FT-IR. After hydrolysis, it was seen that no 3-pentenoic acid was released from [Ti(OPri )3(PA)]n and but was released from [Sn(OBun )3(PA)]n under the studied conditions.
