反応手順
Oxygen was bubbled, at a fast rate, for 3 hours, through a vigourously stirred solution of 2-hydroxydibenzofuran (73.8 g; 0.40 mol), copper (II) acetate (4.60 g; 0.025 mol) and piperidine (79.9 g; 0.94 mol) in methanol (600 ml) at room temperature. The resulting dark reaction mixture was filtered and the collected solid dried in air to give 4-piperidinodibenzofuran-1,2-dione as a very dark blue solid (66.3 g; 59%), m.pt. 151°-6° C. ##STR11##
