Abstract

It is generally acknowledged that in protic organic solvents, 1,2-diamine reacts with 1,2-diketone to form an aromatic compound containing the pyrazine ring. As expected, the condensation reactions of 1,4-bis-[(triisopropylsilyl)ethynyl]naphthalene-2,3-diamine or 1,4-bis[(triisopropylsilyl)ethynyl]anthracene-2,3-diamine with 3,5-di-tert-butyl-1,2-benzoquinone yielded diazatetracene and diazapentacene derivatives. Meanwhile, naphthoazepin and anthroazepin derivatives which contained the imidazole ring were also obtained. Naphthoazepin and anthroazepin derivatives contained a seven-membered ring. All new compounds were characterized by proton and carbon-13 nuclear magnetic resonance spectroscopy, UV-vis spectrophotometry, high resolution mass spectrometry and single crystal X-ray diffraction. The possible reaction mechanisms were proposed as well.
