3]metacyclophane 6. The reaction of the latter dithiol with CH2Br2 afforded the expected 1,3,10,12-tetrathia[3.3]metacyclophane 7 1HNMR and mass spectra of compounds 1–7 are discussed. 1H NMR spectral properties suggest for these compounds either syn or anti conformations, depending on the nature of the bridges and the substitution pattern of the constituent aromatic rings
5,7,14,16四取代hexathia [3.3] metacyclophanes 1 - 4(R = H,Me中的OME,Cl)的已经被适当dithioresorcinol衍生物在SCL偶联合成2,高稀释条件下进行。令人惊讶地,均三甲苯-2,4-二硫醇与SCl 2和S 2 Cl 2的反应给出了异构体hexathia [4.2] metacyclophane 5和更高的同系物庚烷[4.3] metacyclophane 6。后者的二硫醇与CH 2 Br 2的反应提供了预期的1,3,10,12-四硫杂[3.3]甲基环已烷7 1 HNMR和化合物1 –的质谱。讨论图7。1 H NMR光谱性质表明这些化合物具有顺式或反式构型,具体取决于桥的性质和芳族环的取代方式
