Abstract

By means of four-and six-component cyclization reaction various cyclophanes were synthesized. The components were the di (lithium) salts of 1, 4-di (ethynyl) benzene (11), 4, 4′-di (ethynyl) biphenyl (13), 1, 4-di (ethynyl)-2, 5-di (n-hexyl) benzene (18), and 1, 4-di (ethynyl)-2, 5-di (n-propyl) benzene (19). These building blocks were reacted with α, ω- dithiocyanato-n-alkanes and α, ω-diselenocyanato-n-alkanes with n= 3− 6. In the case of ...
