Deskripsi
An efficient synthesis of a series of pyridazino[4,3-<i>c</i>:5,6-<i>c</i>′]diquinolines was achieved via the autoxidation of 4-hydrazinylquinolin-2(1<i>H</i>)-ones. IR, NMR (<sup>1</sup>H and <sup>13</sup>C), mass spectral data, and elemental analysis were used to fit and elucidate the structures of the newly synthesized compounds. X-ray structure analysis and theoretical calculations unequivocally proved the formation of the structure. The possible mechanism for the reaction is also discussed.
