摘要

以十二羰基三钌和o-PPh2C6H4NR2（R=H，Me）配体为原料，成功制备了三种新型羰基钌化合物（μ-o-PPh2-C6H4NH）Ru3（μ-H）（CO）9（2）、（o-PPh2C6H4NH）2Ru（CO）2（3）和（μ-o-PPh2C6H4NMe2）2Ru（CO）3（4）.对这三个化合物进行了核磁共振和红外谱学、元素分析和X射线单晶衍射分析表征，并对这三个化合物进行了催化性能研究.化合物2和4可催化苯甲醛加氢反应生成苯甲醇，但是3没有催化活性.从实验角度阐述了膦胺配体钌催化剂的结构与性能关联，进一步探讨了加氢催化反应失活的可能原因.

Abstract

New carbonyl ruthenium complexes (μ-o-PPh2C6H4NH)Ru3(μ-H)(CO)9 (2), (o-PPh2C6H4NH)2Ru(CO)2 (3) and (μ-o-PPh2C6H4NMe2)2Ru(CO)3 (4) have been successfully synthesized by using ruthenium carbonyl and o-PPh2C6H4NR2 (R=H, Me) ligand. The three complexes have all been characterized by NMR and IR spectroscopies, elemental analysis and X-ray crystallography. Complexes 2 and 4 could catalyze the hydrogenation of benzaldehyde into benzyl alcohol. However, complex 3 showed no activity. This study reveals a correlation between structure and catalytic property, where the possible deactivation mode for the hydrogenation reaction using the aminophosphino ruthenium catalyst is discussed in view of the experimental work.

Key words： aminophosphino ruthenium carbonyl; synthesis and characterization; catalytic hydrogenation; structure and property; deactivation
