摘要

Summary The reaction of ethyl dichloroacetate with alcoholic sodium ethoxide gives a small yield of ethyl diethoxyacetate plus larger quantities of ethyl oxalochloroacetate diethyl acetal. The latter compound loses alcohol readily on heating, giving ethyl a-chloro-P- ethoxymaleate, from which the corresponding substituted maleic acid and anhydride have been prepared.
