摘要：
The influence of diastereoisomerism on the electrochemical behaviour of the atropisomeric cyclophanes la and Ib was found by cyclovoltammetric studies, Compound la can be oxidized and reduced reversibly in a two step redox process similar to that of model compound 2, In contrast, Ib shows a different electrochemistry, As a result of a detailed investigation of Ib a complex reaction scheme can be postulated starting with a chemical reaction after the first oxidation step, The special spatial situation in Ib makes possible this EC mechanism reaction, which does not occur in la or in unbridged biindolizines.
