dc.description.abstract[中文文摘]系统地比较了FeMo-co和固氮酶的各种模拟体系在KBH_4还原乙炔为乙烯的反应中的催化活性和选择性。FeMo-co(活性:转变数为34;选择性:99%C_2H_4)和本实验室合成的模型化合物(活性:转变数为20~30;选择性;91~95%)比其它固氮酶的模拟体系(MoO_4~(2-)-CySH;MoO_4~(2-)—CySH—Fe~(2+);MoOS_4~(2-)—胰岛素;[Fe_4S_4(SCH_2Φ)_4]~(2-);和MoS_4~(2-))具有较高的活性和选择性;这可作为FeMo—co及其合成模拟物的原子簇活性中心多核络合活化底物分子的一种判据.[英文文摘]The catalytic activities and sclectivities of FeMo-co and various nitrogenase-modeling systems in the reduction of acetylene to ethylcne by KBH4 have been compared. The high selectivities and high activities of FeMo-co (activity: turn-over number 34 min-1, selectivity: 99% C2H4) and the modeling compounds synthesized in this laboratory (activity: turnover number 20-30 min-1, selectivity: 91-95%), in comparison with many other nitrogenase modeling systems (MoO24-CySH, MoO42--CySH-Fe2+, MoO42--insulIN, [Fe4S4(SCH2Φ)4]2- and MoS4(2-)),may be regarder as a criterion indicating polynuclear coordination activation of the substrate molecules on cluster active-center of FeMo-co and of the synthetic modeling compounds.zh_CN
