A stereoselective, denitrative cross-coupling of β-nitrostyrenes with N-alkylpyridinium salts for the preparation of functionalized styrenes has been developed. The visible-light-induced reaction proceeds without any catalyst at ambient temperature. Broad in scope and tolerant to multiple functional groups, the moderately yielding transformation is orthogonal to several traditional metal-catalyzed

吡啶盐的立体选择性、反硝化交叉偶联已被开发出来,用于制备官能化
苯乙烯。在环境温度下,可见光诱导的反应在没有任何催化剂的情况下进行。范围广泛并能容忍多个官能团,适度产率的转变与几种传统的
