Complexation reactions of titanium tetraethoxide [Ti(OEt)4] and titanium tetra-n-butoxide [Ti(OBun)4] with 3-pentenoic acid (PA) and allylacetoacetate (AAA), in a 1 : 1M ratio, were studied in ethanol solution at room temperature.13C-NMR and FTIR spectra showed that all PA and AAA completely reacted with both titanium alkoxides. Hydridosilane compounds such as triethoxysilane and triethylsilane were added to titanium chelate complexes in a 1 : 1M ratio. The investigation of products by13C- and29Si-NMR and FTIR showed additions of SiH to the CC double bond. The hydrolysis of titanium-PA and AAA complexes, by water in 1 : 4 ratios, resulted in released PA in an amount of 10% and AAA of 20%. The stability of hydrolyzed products was investigated by13C-NMR,29Si-NMR, and FTIR.
