  摘要：

  在最近的过去，可见光介导的光氧化还原催化在非常温和和生态良好的条件下对新合成方法的开发产生了巨大的影响。尽管半导体纳米晶体或量子点（QD）具有适合光氧化还原催化应用的光电和氧化还原特性，但令人惊讶的是，很少探索将其用于活化有机分子合成中具有挑战性的化学键。我们在此报告ZnSe / CdS核/壳量子点在脱卤和CH芳基化反应中使用重要的光-氧化还原催化碳-卤键的应用，该反应使用（杂）芳基卤化物作为稳定的廉价廉价散装原料，反应条件温和。

  arylation of pyridylsulfides with good functional group tolerance was developed. To demonstrate synthetic utility, the resulting pyridylsulfonium salts were used in a scalable transition-metal-free coupling protocol, yielding functionalized bipyridines with extensive functional group tolerance.

  This work emphasizes the synthesis of substituted vinyl arenes by reductive coupling of aryl halides with vinyl bromides under mild and easy‐to‐operate nickel‐catalyzed reaction conditions. A broad range of aryl halides, including heteroaromatics, and vinyl bromides were employed to yielding products in moderate to excellent yields with high functional‐group tolerance. The nickel‐catalytic system displays
