Preparatively satisfactory routes to [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 available in gram quantities allowing a study of their chemical properties.(© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009)
