Active Lewis pairs contain donor and acceptor atoms, which are connected by relatively weak bonding interactions. Cleavage of these bonds results in the formation of molecules with coordinatively unsaturated Lewis acidic and basic centers, which cause a unique reactivity with the coordination or cooperative activation of various substrates. Three examples may illustrate their promising properties: (i) They are able to activate carbon-hydrogen bonds which currently is a highly interesting research field. (ii) The simultaneous formation of two carbon-carbon bonds was observed upon treatment with an isocyanate. (iii) Oligomerisation or polymerisation reactions with polar monomers succeeded under mild reaction conditions already below room temperature.

活性路易斯对包含供体和受体原子，它们通过相对较弱的键合相互作用连接。这些键的断裂导致形成具有配位不饱和路易斯酸性和碱性中心的分子，从而通过各种底物的配位或协同活化产生独特的反应性。三个例子可以说明它们有前景的特性：（i）它们能够激活碳-氢键，这是目前非常有趣的研究领域。 (ii)用异氰酸酯处理时观察到两个碳-碳键同时形成。 (iii)与极性单体的低聚或聚合反应在已经低于室温的温和反应条件下成功。
