Reactions of Aromatic Diazonium Salts with Diethyl Sodiomalonate

Benzenediazonium chloride and m-toluenediazonium chloride react with sodium salt of diethyl malonate in aqueous ethanol to give the coupling products (I and V) as the major products, along with the products (II, III, IV, VI) apparently derived from the coupling products.All the products obtained have been fully characterised by IR and PMR data.
