  Synthesis of Substituted Dibenzoequinenes

  摘要：

  The naphthalenophanes with four donor groups such as 4,7,14,17-tetramethoxy-anti-[2.2](1,4)naphthalenophane (10), the corresponding syn-isomer 10a, and 4,7,14,17-tetramethy1-anti-[2.2](1,4)naphthalenophane (17) together with the naphthalenophanes with four acceptor groups, 4,7,14,17-tetracyano-anti-[2,2](1,4)naphthalenophane (21), and 5,6,15,16-tetracarbethoxy-anti-[2.2](1,4)naphthalenophane (23), belonging to point group C-2h for the anti-and C-2v for the syn-isomer, have been synthesized following mostly known procedures. Furthermore, the preparation of 5,6-dicarbethoxynaphthaleno-[2.2](1,4)naphthalenophane (27) and 2,5-dimethoxynaphthaleno-anti-[2.2](1,4)-5,8-naphthochinonophane (28) with one donor and one acceptor substituted ring supplements the series. The irradiation of 10, 21, 23, and 27 yields 2,2',5,5'-tetramethoxydibenzoequinene (30), 2,2',5,5'-tetracyanodibenzoequinene (31), 3,3',4,4'-tetracarbethsxydibenzoequinene (32) and 3,4-dicarbethoxydibenzoequinene (33). Structural investigations on 30 by means ofthe X-ray method show a strong folding of the cyclobutane rings. The average bond length of the four-membered rings in 30 was found to be 1.579(2) Angstrom. The values obtained for the bond lengths and bond angles resemble those of the parent system 2. Long ethano bonds (1.556-1.591 Angstrom) in the bridges were found in the synand anti-naphthalenophanes 10a, 14, and 17 by means ofX-ray structure analysis.
