| 2.將PPh3配體換成2,2′–聯(lián)吡啶配體合成了一種水溶性過渡金屬釕氫氧根配合物Cis-[(bipy)2Ru(OH)(H2O)](OTf)，對(duì)中間物cis-[RuⅡ（bpy）2Cl2]•2H2O的結(jié)構(gòu)進(jìn)行了詳細(xì)的分析，并探討了Cis-[(bipy)2Ru(OH)(H2O)](OTf)的合成工藝及其催化水化乙腈和末端炔烴的反應(yīng)機(jī)理。實(shí)驗(yàn)表明，Cis-[(bipy)2Ru(OH)(H2O)](OTf)對(duì)乙腈的轉(zhuǎn)化率要高于TpRu(PPh3)2（OH），且對(duì)水和空氣非常穩(wěn)定。 |

| Water-soluble transition metal complexes of ruthenium hydroxide Cis-[(bipy)2Ru(OH)(H2O)](OTf) has been synthesized by exchange PPh3 ligand with 2,2 '- bipyridine ligands, the structure of the Intermediate cis-[RuⅡ（bpy）2Cl2]•2H2O was under detailed analysis, synthesis technics of Cis-[(bipy)2Ru(OH)(H2O)](OTf)and catalytic hydration of acetonitrile and the reaction mechanism of terminal alkynes have been discussed. The experiments results showed that Cis-[(bipy)2Ru(OH)(H2O)](OTf) for the conversion of acetonitrile higher than TpRu (PPh3) 2 (OH) and has higher stability with the existence of water and air. |
