benzotriazole-pyridinyl-silane ligand (BPS) was designed, and the corresponding iridium and copper catalysts were synthesized and thoroughly characterized by means of EDS, TEM, and XPS. The resulting iridium composite revealed excellent catalytic activity for the reaction of tert-butanesulfinamide with benzyl alcohols, while copper catalyst could realize the synthesis of unsaturated carbonyl compounds through
高活性配体通常在催化和合成化学过程中起重要作用。设计了一种新型高效的苯并三唑-吡啶基-硅烷配体(BPS),合成了相应的铱和铜催化剂,并通过EDS,TEM和XPS对其进行了全面表征。所得铱复合材料对叔丁烷亚磺酰胺与苄醇的反应显示出优异的催化活性,而铜催化剂可通过苄醇与酮的反应实现不饱和羰基化合物的合成。这提供了一种从苯甲醇和酮中高收率选择性合成不饱和羰基化合物的有效方法,具有良好的回收性能。
