The present invention discloses a method for preparing a catalyst system for hydrogen cyanide butadiene or one or more monoolefins mono nitriles. The method comprises the following steps: reacting metal nickel, at least one bidentate organophosphorus ligand and at least one formula P (XaRa) (XbRb) (XcRc) compounds in the presence of a liquid diluents in a single step; wherein Xa, Xb and Xc are each independently oxygen or a single bond; Ra, Rb and Rc are each independently an alkyl group having 1 to 10 carbon atoms or an aryl group having 1 to 20 carbon atoms. 本发明公开种制备用于氢氰化丁二烯或或多种单烯烃单腈的催化剂系统的方法，所述方法包含使金属镍、至少种双牙有机磷配体和至少种式P(XR)(XR)(XR)化合物在液体稀释剂存在下在单步中反应；其中X、X和X各独立地为氧或单键；且其中R、R和R各独立地为具有1到10个碳原子的烷基或具有1到20个碳原子的芳基。
