包容性极强的NO2(硝基)还原为NH2(氨基)方法 硝基还原是制备脂肪胺和芳香胺最常用的方法之一,最经典的方法是金属如Pd/C, PtO2, Raney Ni等催化的氢化还原反应,此外转移氢化也是比较常用的条件。除此之外,Zn粉,Fe粉等参与的硝基还原反应也很常用。尽管方法很多,寻找更加绿色,无金属参与以及高官能团包容性的还原方法...

palladium(II) complex supported by multiwall carbon nanotubes, silicon dioxide, and iron(II,III) oxide (Fe3O4) were fabricated by a simple-impregnation methodology, characterized by FT-IR, BET, TEM, and XRD techniques and investigated for their catalytic performance for the same reaction. Thus...
1. The -NO2 group can be reduced to the -NH2 group through a hydrogenation reaction, typically conducted in the presence of iron powder and hydrochloric acid (FeCl2).2. Under acidic conditions, the cyano group -CN can be hydrolyzed, resulting in the formation of the carboxyl gro...
The rate coeffcients of the NH2+NO2 reaction do not agree with the rep- orted results. Our results also show both two reactions are p- ressure independent and have negative temperature dependence. 展开 年份: 1994 收藏 引用 批量引用 报错 分享 ...
Reactions of NH2 with NO2 and of OH with NH2O The reaction system produced by 193 nm flash photolysis of a mixture of NH3 and NO2 has been investigated experimentally and modeled. The accepted belief t... F Sun,JD Desain,G Scott,... - 《Journal of Physical Chemistry A》 被引量: ...
An ab initio molecular orbital study of potential energy surface of the NH2+NO2 reaction Potential energy surface of the reaction of NH2with NO2has been studied at the QCISD(T)/6‐311G(d,p)//MP2/6‐311G(d,p)+ZPC[MP2/6‐311G(d,p)] andGAUSSIAN2 (... AM Mebel,CC Hsu,MC Lin...
NH3 和 SiCl4 的反应是一种重要的化学反应。在该反应中,氨气和 四氯化硅可以结合形成氨基硅烷化合物(通常命名为氨基硅烷或硅氨 烷),其化学式为 SiH3NH2。反应方程式如下: SiCl4 + 4NH3 → SiH3NH2 + 4HCl 这个反应方程式描述的是,当四氯化硅与氨气反应时,四氯化硅 中的氯离子和氨气中的氢离子结合形成氯化...
