铝汞齐的制作及注意? 我查了一篇文献,是关于用铝汞齐作为催化剂来还原硝基为羟胺的,出处是synthesis 1995 1053。叙述如下: aluminum foil(8g 0.3mol)was amalgamated as follows:the foil was folded 3-4 times and cut into strips of about 1 cm2.then,the foil was treated with a 3% aqueous hgcl2,washed several times with water,3 times with meoh,and 3-4 times with thf.the amalgamated aluminum was covered with thf(90ml), cooled to 0℃, and water(10ml) was added.a solution of 2-methyl-2-nitro-1-phenylpropane(5.4g,0.03mol) in thf(25ml) was added dropwise to this mixture maintaining the temperature below 5℃ over a period of 20 min.the liquid phase was decanted after 15 min, and the residue washed with thf (4×). the combined organic extract was dried(mgso4),and the solvent was distilled to give a residue(5.6g),which contained traces of amine.crystallization of the residue from hexane afford(64%) pure n-hydroxylamine. 本来想把它翻译成中文的,但是怕自己翻译得不好造成大家的误解,所以就直接把原文搬过来了,以供大家参考。同时希望用过铝汞齐的前辈们能够给我一些指导,在此我深深的感谢大家,尤其是以前给过我建议的 way107 查看更多
