Abstract
Abstract The more hindered monoacetates were selectively formed in the presence of silica gel with acetyl chloride by refluxing a suspension of unsymmetrical diols containing a primary hydroxyl group such as 1, 5-hexanediol preadsorbed on silica gel. Such regioselectivity was observed through preferential adsorption via a primary hydroxyl group of the diols. Copyright© 2003 John Wiley & Sons, Ltd.
