[3.2]paracyclophane (10), [4.2]paracyclophane (14), [4.3]paracyclophane (19) as well as several derivatives of these compounds – among others the bromides 25, the ester 31, the diesters 40–43 – are described using well-established methods of cyclophane chemistry (ring-closure reactions leading to thiacyclophanes, ring contraction by sulfone pyrolysis). The parent systems and their derivatives are now
制备 [3.2] 对环烷 (10)、[4.2] 对环烷 (14)、[4.3] 对环烷 (19) 以及这些化合物的几种衍生物——其中包括溴化物 25、酯 31、二酯 40——的令人满意的路线43 – 使用成熟的环芳化学方法(导致硫环芳烃的闭环反应,砜热解引起的环收缩)进行描述。母体系统及其衍生物现在可提供克级数量,可用于研究它们的化学性质。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009)
