With the characterization of NMR and IR, combining with the synthesis of active species and studies of their structures, it is suggested that the hydride [RuHCl(PPh3)3], being favorably formed in the acid media, exhibited higher activity in the reduction of the C=C bond, while the hydride [RuH4(PPh3)3], being preponderantly formed in the basic media, showed activity and higher selectivity towards the C=O reduction.

通过核磁、红外等表征手段，并结合可能催化活性配合物的合成和结构研究，推测了在非水介质中对C=C和C=O双键起到活化作用的催化剂活性物种和可能的选择加氢反应机理，即，催化剂[RuCl2(PPh3)3]在酸性环境下倾向于生成[RuHCl(PPh3)3]物种，该Ru-H物种对C=C双键加氢反应表现出较高的活性；而碱性环境下则易于生成[RuH4(PPh3)3]物种，该Ru-H物种对C=O双键加氢具有较高的催化活性。
