between methyl butyrate and 1,n-diol monoacetates: the ethylene glycol derivative sluggishly undergoes transesterification whereas higher homologs react smoothly. The unique template effects of the catalysts are discussed in terms of cooperation of to different tin atoms which are located in the proximity.

there is a compromise between the reactionselectivity and the surface physicochemical properties of the employed catalyst. Our results clearly show that the catalyst having high surfacehydrophilic nature gives high selectivitytoward the formation of mono-acylated products whereas those with relatively high hydrophobic characteristics showed enhanced selectivitytoward the formation of di-acylated products
Selective acylation of a sterically hindered hydroxyl group of unsymmetrical diols containing a primary hydroxyl group such as 1,5-hexanediol in the presence of silica gel with acetyl chloride
