氨水与锌粉反应生成什么 放出氢气,并生成氢氧化四氨合锌[Zn(NH3)4](OH)2 http://zhidao.baidu.com/question/78733782.html 粘贴一下:肟的还原在教科书中写的都很简单,但其实变化是比较复杂的。可能的产物有肟还原为胺,亚胺,饱和烷基,或由肟水解为原来的酮基。可能的还原条件有很多,锌+醋酸,硼氢化钠,硼氢化钠+lewis酸,LAH,Pd催化氢化,Pd+甲酸铵,Raney-Ni,铝镍合金,Na+醇.如果没有文献参考,就要摸一下条件了。
有机化学实验中常用的还原剂有哪些 NaBH4 硼氢化钠乙硼烷9-BBN儿茶酚硼烷LiAlH4 氢化铝锂(四氢铝锂)Red-Al 二氢双(2-甲氧乙氧基)铝酸钠H2,催化剂(包括 Pd/C,Pd(OH)2,Ni,Raney Ni,Wilkinson's,CuCrO4。
如何实现铑的液相还原 可以采用甲醛还原、乙二醇还原,可以制备出比较均匀的金属纳米颗粒。而水合肼和硼氢化钠的还原能力过强,还原出来的金属颗粒大而且不均匀!可以参考:Ni2O3-around-Pd hybrid on graphene oxide:An efficient catalyst for ligand-free Suzuki–Miyaura coupling reactionApplied Catalysis A:General,Volume 473,5 March 2014,Pages 1-6Selective hydrogenation of cinnamaldehyde over reduced graphene oxide supported Pt catalystCatalysis Communications,Volume 41,5 November 2013,Pages 101-105Selective oxidation of glycerol with oxygen in base-free solution over MWCNTs supported PtSb alloy nanoparticlesApplied Catalysis B:Environmental,Volume 127,30 October 2012,Pages 212-220Platinum supported on reduced graphene oxide as a catalyst for hydrogenation of nitroarenesCarbon,Volume 50,Issue 2,February 2012,Pages 586-596Selective oxidation of glycerol with oxygen in a base-free aqueous solution over MWNTs supported Pt catalystsApplied Catalysis B:Environmental,Volume 106,Issues 3–4,11 August 2011,Pages 423-。
