For the first time it was possible to induce the cation-radical Diels-Alder reaction between electronrich dienes and electronrich dienophiles electrochemically, thus providing a clearer view upon the mechanism of this reaction type. In contrast to common explanations it could be demonstrated that this reaction most probably takes place via the cation radical of the diene. A role selectivity towards
首次有可能电化学诱导富电子二烯和富电子二烯亲电子之间的阳离子自由基Diels-Alder反应,从而使这种反应类型的机理更清晰。与通常的解释相反,可以证明该反应最有可能通过二烯的阳离子自由基发生。可以排除对亲双烯体阳离子自由基的作用选择性。
