Titanium tetra-n-butoxide

The influence of temperature on the ortho effect has been evaluated in the alkaline hydrolysis in aqueous DMSO solutions of ortho-, meta- and para-substituted phenyl benzoates (26). The alcoholysis of phthalic anhydride (27) to monoalkyl phthalates (28) occurs through an A-2 mechanism via rate-determining attack of the alcohol on a carbonyl carbon of the anhydride (Scheme 4). Evidence adduced for this proposal included highly negative A 5 values and a p value of 4-2.1. In the same study, titanium tetra-n-butoxide and tri-n-butyltin ethanoxide were shown to act as effective catalysts of the half-ester formation from (27), the mechanism involving alkoxy ligand exchange at the metal as an initial step. ...

Martin and Winter" also observed three-fold molecular complexity for titanium tetra-n-butoxide and the molecular weight was shown to be concentration dependent. The replacement of butoxy groups by the more electronegative chlorine atoms appears to affect the molecular complexity of tetra-n-butoxide considerably. Thus it has been observed that the trimeric titanium monochloride tributoxide does not... 

The reactions of metal alkoxides with halogens were investigated by Nesmeyanov et al. who observed that the reaction between titanium tetra-n-butoxide and chlorine or bromine yielded the dihalide dibutoxide coordinated with one mole of alcohol as TiX2(OBu)2.BuOH and n-butyl propionate. The reaction may be represented by... 

Numerous titanium alkoxides are used in sol-gel chemistry, in order to prepare inorganic titanium oxides. They are, for instance, Ti tetra-iso-propoxide (TIPT) and Ti tetra-n-butoxide (TBOT). The sol-gel transformation mechanisms of TIPT-derived coatings have been qualitatively studied by FUR spectroscopy (Burgos and Langlet, 1999), allowing a good knowledge of the hydrolysis and condensation reactions of the aUcoxide.
