Catch it! Geminal phosphorus/aluminum‐based frustrated Lewis pairs (FLPs) are easily obtained by hydroalumination of alkynylphosphines. These FLPs can activate terminal acetylenes by two competitive pathways, which were analyzed by DFT calculations, and they can bind carbon dioxide reversibly. Therefore, alongside polyfluorinated boranes, alanes are also ideal Lewis acids for FLP chemistry.
抓住它!通过磷化炔基膦很容易获得基团磷/铝基沮丧的路易斯对(FLP)。这些FLP可以通过两种竞争途径激活末端乙炔,并通过DFT计算对其进行了分析,并且它们可以可逆地结合二氧化碳。因此,除了多氟硼烷以外,丙氨酸也是FLP化学的理想路易斯酸。
