実験手順
A solution of ferrous sulfate heptahydrate (496 g) in water (1080 ml) and tert-butylhydroperoxide (173 ml) were simultaneously added to a solution of 4-pyridinecarbonitrile (30 g), acetaldehyde (97.6 ml) and sulfuric acid (15.4 ml) in water (90 ml) at 0° C. with stirring. After stirring at the same temperature for one hour, the resulting precipitate was collected by filtration and washed with water to give 2-acetyl-4-pyridinecarbonitrile (22.5 g).
