One pot direct synthesis of β-ketoesters via carbonylation of aryl halides using cobalt carbonyl

A direct method for the synthesis of beta-ketoesters from aryl halides (iodide, bromide) has been described by using cobalt carbonyl as carbon monoxide source in microwave irradiation. Using this protocol, a wide variety of substituted aryl halides has been successfully converted to corresponding beta-ketoesters. (C) 2014 Elsevier Ltd. All rights reserved.
