首次用邻苯二磺酰亚胺作为布朗斯台德酸催化剂，诱导二烯酮电环化生成环戊烯酮（Nazarov反应）。该催化剂已在各种有机溶剂中或在无溶剂条件下使用，并且其可从反应混合物中完全回收。所提出的程序的通用性和有效性被证明在广泛的活化和灭活底物。
o-Benzenedisulfonimide has been used for the first time as a Bronsted acid catalyst to induce electrocyclization of dienones into cyclopentenones (Nazarov reaction). The catalyst has been used in various organic solvents or under solvent-free conditions and it is entirely recoverable from the reaction mixture. The versatility and the effectiveness of the proposed procedure is demonstrated on a wide range of both activated and inactivated substrates.
