Chemistry of Heterocyclic Compounds Aims and scope

Abstract

The dependence of the rate and selectivity of the catalytic hydrodehalogenation of ethyl 2,5-dichloro-3-thienylglyoxylate over immobilized palladium complexes on the nature of the solvent and HC1 acceptor has been investigated. Hydrogenation of the C=0 group also occurs. Reductive dechlorination of methyl and ethyl 2,5-dichloro-3-thienylacetates occurs selectively, at a slower rate than in the case of the 3-thienylglyoxylate.
