金屬有機催化劑中,配體發揮著關鍵作用,不同的配體通過穩定及激活中心金屬原子,能夠在催化反應中發揮選擇性的催化作用。
根據給體原子或子結構的差異分為:膦配體/ Phosphine Ligands、Salen配體/ Salen Ligands、氮雜環卡賓配體/ N-Heterocyclic Carbene Ligands、烯配體/ Ene Ligands、二酮配體/ Diketone Ligands、胺配體/ Amine Ligands、亞胺配體/ Imine Ligands、吡啶配體/ Pyridine Ligands、聯吡啶,三聯吡啶配體/ Bipyridine & Terpyridine Ligands、菲咯啉配體/ Phenanthroline Ligands;
在以上多種配體中,膦配體在偶聯反應中扮演者最為廣泛且重要的作用,如經典的Suzuki Coupling、Stille Coupling、Negishi Coupling、Heck Reaction;
