Complexation reactions of titanium tetraethoxide [Ti(OEt)(4)] and titanium tetra-n-butoxide [Ti(OBu")(4)] with 3-pentenoic acid (PA) and allylacetoacetate (AAA), in a 1 : 1M ratio, were studied in ethanol solution at room temperature. C-13-NMR and FTIR spectra showed that all PA and AAA completely reacted with both titanium alkoxides. Hydriclosilane compounds such as triethoxysilane and triethylsilane were added to titanium chelate complexes in a 1 : 1M ratio. The investigation of products by C-13- and (SiNMR)-Si-29 and FTIR showed additions of -SiH to the C=C 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 by C-13-NMR, "SiNMR, and FTIR. (C) 2004 Wiley Periodicals, Inc.
