仿生金–硫族键协同催化平台实现可切换活化与动态官能团采样
A Bioinspired Gold–Chalcogen Bonding Synergistic Catalysis Platform: Switchable Activation and Dynamic Functional Group Sampling
AI 导读
研究报道了一种金–硫族键协同催化平台，其双功能催化剂可在硫族位点与金位点之间切换活化中心，并借助互补部分提供邻近效应。硫族键带来的动态官能团采样使催化剂能正交识别烯烃与炔烃等相似官能团，从而直接由醇加成到多取代烯烃（包括全取代变体）合成位阻醚，并延伸至色胺与炔烃衍生物经环化路径的新聚合反应。对照实验显示这些转化在金催化或硫族键催化单独作用下均不发生。
推荐理由
该平台通过硫族键与金的协同切换活化中心，使醇加成到多取代烯烃和色胺环化聚合在单一催化体系下实现。
