Abstract:A direct and catalytic dehydrative esterification of carboxylic acids with alcohols is described. B(C 6 F 5 ) 3 is shown to be a highly effective catalyst for the Fischer esterification, providing esters in high to excellent yields. This esterification shows excellent chemo-and site-selective monoesterification of various polyols without any protection step, including bio-derived molecule glycerol.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
