実験手順
4-Phenanthrenemethanol (Aldrich, 29 g, 0.14 mol) was treated with pyridinium chlorochromate (PCC) (Aldrich, 45 g, 0.21 mol) in CH2Cl2 (2000 mL). After 6 h at RT, the reaction mixture was filtered through a plug of SiO2 to give after removal of solvent and drying and crystallization from CH3OH, 20.5 g (71%) of phenanthrene-4-carboxaldehyde mp 82.5°-84.5° (C,H).
