実験手順

9 g of pentafluorobenzaldehyde are condensed on 7 g of diethyl malonate in accordance with the process described in Organic Synthesis vol. III, page 377. 10 g (69%) of diethyl pentafluorobenzylmalonate are obtained which is hydrogenated at ordinary pressure in the presence of palladium on charcoal into diethyl pentafluorobenzylmalonate (92%).
