查询词典 azide

Furthermore, during the above synthetic studies, we also found sodium amalgam was a useful agent for reducing azide to amine, which was applicable for various alkyl and aryl azides bearing different functional groups.

另外，我们还对实验中意外发现的钠汞齐还原叠氮的反应进行了研究，考察了考察了带有不同官能团的叠氮化合物在此体系下的还原反应，取得了较好的结果，发展了一种新的还原叠氮的方法。

Comparable experiments employing p-toluenesulfonyl azide demonstrated thereaction specialty of fluoroalkamesulfonyl azides.

在同其碳氢类似物如对甲苯磺酰叠氮的对比实验中，还进一步证明了氟烷基磺酰叠氮的反应特殊性。

Therefore, the pre-fabricated functional surface containing azide groups can be covalently anchored through click-chemistry by newly designed acetylene-appended HBCs. These HBC derivatives not only possess the potential in the formation of SAM, but their alignment modes of edge-on or face-on could be controlled by tailor-made molecular design.

因此，我们设计出末端带有乙炔官能基之HBC分子，希望在预先处理并带有叠氮(-N3)官能基的基板表面上进行click-chemistry (速配组合式化学、点击化学)，利用共价键之形式将HBC分子镶嵌於基板表面，除了藉此制作出分子自组装单层薄膜之外，利用分子设计进一步控制其排列方式为edge-on或是face-on。

Using the same low concentration of cell but autoclaved or treated with sodium azide, approximately 83% of 0.5um CIET adsorbed within 3 to 5 min. Sorption of CIET to R01 seem to be passive, since dead cell sorbed as well as live cells.

菌株R02细胞提取物在1 小时内将90％CIET转化为水溶物，粗提物能在－70C下贮存几个月而不失活，但煮沸过的细胞提取物对CIET不起降解作用，这说明菌株R02的可溶酶能转化CIET。

The coordinated COD of 3 and 4 can be replaced by carbon monoxide to yield the corresponding dicarbonyl species [(C,N-pyN^C-R) M2]BF4 (14, M= Rh; 15, M= Ir). Ligand substitution of 11a by phosphines and azide causes the de-complexation of pyridinyl-nitrogen donor to generate the corresponding carbene rhodium complexes [(C-pyN^C-Mes)RhPR3] (17a, R = Ph, 17b, R = Et) and [RhN3] (19), respectively, indicating the labile nature of steric-hindered pyridinyl-nitrogen donor.

螯合错合物的吡啶配位，可以容易被σ-予体，如卤离子、叠氮阴离子、膦试剂，置换；但是铑与铱金属螫合物与π-酸试剂，如一氧化碳、异腈，则发生COD被置的产物14a与16；与三甲基亚磷酸酯反应时，COD及吡啶均会被取代而得到单芽的三铑-碳烯错合物18；双膦化合物则会取代铑金属上全部的配位基。
