Spectroscopic Investigation on the Reactions of Tin and Titanium Alkoxides with 3-Pentenoic Acid

Abstract

Tin and titanium pentenoate have been prepared from tin(IV) butoxide and titanium (IV) isopropoxide in alcohol and 3-pentenoic acid. Reactions of Sn(OBu n )4 and Ti(OPr i )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 13 C, 1 H- NMR and FT-IR spectroscopy. 13 C{ 1 H}, 1 H-NMR and FT-IR spectra showed that 3-pentenoic acid completely reacted with Sn(OBu n )4 and Ti(OPr i )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 13 C, 1 H NMR and FT-IR. After hydrolysis, it was seen that no 3-pentenoic acid was released from (Ti(OPr i )3(PA))n and but was released from (Sn(OBu n )3(PA))n un- der the studied conditions.
