Abstract
Disclosed herein is a very efficient method to make 5-(alkoxycarbonyl)furan-2-carboxylic acids (ACFC) from feedstocks comprised of furoates. When a feedstock comprised of methyl 5-methylfuran-2-carboxylate (MMFC) is used a product comprised of (5-(methoxycarbonyl)furan-2-carboxylic acid (MCFC) is obtained in high yield.
