  摘要：

  As part of our studies on the tetramerization of quinodimethane 1 to the macrocyclic compound 2, the influence of substituents on this reaction was investigated. It was found that a large range of substituents such as 2-phenylethyl, 2-(4-methoxyphenyl)ethyl, 2-(4-fluorephenyl)ethyl, 2-[4-(tert-butyl)phenyl]ethyl, and 2-[4-(2-phenylethyl)phenyl]ethyl, attached at positions 2 and 7 of 9H-fluorene, do net prevent the tetramerization. The key step in the formation of the macrocylic compounds 13a-e is the debromination of 12a-e with mercury to the corresponding quinodimethanes which undergo a self-assembly forming 13a-e in high yields To study the conjugative influence of substituents on tetramerization, the effect of the hex-1-ynyl groups at positions 3 and 6 of the 9H-fluorene rings was investigated. In this case, the corresponding macrocycle 17 was generated by the reaction of diol 16a with SnCl2. Although the expected tetramerization to 17 occurred, the yield was lower than in the case of 13a-e, due to the sensitivity of the product.
