With the single exception of anthracene, which yields the unsymmetrical adduct (VA), olefins, polyenes and aromatic compounds react with tetracyanoethylene oxide to give symmetrical 2,2,5,5-tetracyanotetrahydrofurans. With the more nucleophilic olefins, including anthracene, oxygen transfer also occurs, forming ketones and tetracyanoethylene or its adducts with the olefin.
除了产生非对称加合物(VA)的蒽外,烯烃,多烯和芳族化合物与四氰基环氧乙烷反应生成对称的2,2,5,5-四氰基四氢呋喃。对于更多的亲核烯烃,包括蒽,也会发生氧转移,从而形成酮和四氰基乙烯或其与烯烃的加合物。
