The chemical reactivity of metal alkoxides offers a broad range of possibilities for chemical modification of these molecular precursors. The whole hydrolysis-condensation process may then be completely different leading to new products. An analysis is presented concerning some of the most common ...

According to the results, most of the samples pretreated with zirconia layers showed a good performance, even better than commercial chemical treatments, when acetic acid was used as a modifier of the alkoxide precursors.doi:10.1163/15685610152540858...

Thioesters have been found to be more reactive then the corresponding oxoesters towards most nucleophiles (with the notable exception of hydroxide and alkoxides). The enhanced reactivity of thioesters may be due to a poor C-S p overlap that lowers the overall thermodynamic stability of the ...
process arises from the unique reactivity of thioesters that renders them ideal intermediates for acyl transfer processes. Thioesters have been found to be more reactive then the corresponding oxoesters towards most nucleophiles (with the notable exception of hydroxide and alkoxides). The enhanced ...
Fig. 1 illustrates the typical CSD process together with a number of variations that are frequently employed. The process starts with the preparation of suitable precursors that are often salts, typically, carboxylates, or other metallo-organic compounds, usually, alkoxides (Section 2). The precurs...
