A Cu(II)-catalyzed Csp 2 -Se and Csp 2 -Sulfur bond formation was achieved with moderate to good yields without the aid of Lewis acid and base. The reaction is compatible with a wide range of heterocycles such as benzothiazole, thiazole, and imidazole. Also, this typical protocol is found to be active in thio-selenation via S-H activation. Additionally, we proposed a plausible mechanistic pathway involving Cu(III) putative intermediate.

路易斯酸/无碱合成2-芳硫基和烯丙基苯并噻唑/噻唑和咪唑的策略

在不借助路易斯酸和碱的情况下，以中等至良好的产率获得了Cu（II）催化的Csp 2 -Se和Csp 2-硫键的形成。该反应与各种杂环相容，例如苯并噻唑，噻唑和咪唑。同样，发现这种典型的方案在通过SH活化的硫代硒化中是有效的。此外，我们提出了一种可能的机制途径，涉及推测的中间体Cu（III）。
