5-Methyl-, 5-chloro-, 3-chloro-5-methyl-2-methoxybenzophenones have been condensed with ethyl bromoacetate and ethyl a-bromopropionate under Reformatsky's condition to yield hydroxy esters which have been dehydrated to the unsaturated esters and the latter on demethylation give quantitative yields of courmarin derivatives
