对溴苯腈制备

①氰化亚铜复盐溶液 208g(2.1mol)氯化亚铜悬浮于1L水中,然后将355g(98%,7.1mol)氰化钠溶于1L水的溶液在搅拌下加入,氯化亚铜变为氰化亚铜,继而与过量的氰化钠和用生成复盐络合物而溶解(无色),反应放热,但无须冷却。
②重氮化 800mL水中加入200mL(相对密度1.15,31%)盐酸,加热至70℃,搅拌下加入345g(2mol)对溴苯胺,充分搅拌即在盐酸盐而溶解,再加入200mL工业盐酸,冷后即析出细小结晶。内加冰控制6℃左右,用分液漏斗从液面下搅拌着、慢慢加入142g(2mol)亚硝酸钠溶于200mL水的溶液。加完后继续搅拌10min,此时反应物体积3L(有少量悬浮的未溶,看起来很多,过滤却是很少的悬浮物,为重氮氨基化合物)。搅拌下将此重氮盐溶液慢慢加入至温热50~60℃的氰化亚铜溶液中去,立即反应,放出氮气。最初加入1/3的重氮盐溶液生成物为棕红色油状物(流体),继续加入不久即形成棕红色固体物质,加完后再搅拌0.5h。放置3h后滤出,水洗,风干后得360g产物。将棕红色产物在2L三口烧瓶中,加入20g亚硫酸氢钠进行水蒸气蒸馏,至无结晶蒸出为止(约6h)收集至6~8L馏出液,滤出结晶,风干后得210g产物。熔点102~110℃。

Tetragonal Cu2Se nanoflakes: synthesis using selenated propylamine as Se source and activation of Suzuki and Sonogashira cross coupling reactions.

Dalton Trans. 44(2) , 725-32, (2014)

The metastable tetragonal Cu2Se phase as nanoflakes has been synthesized for the first time by treating CuCl2 taken in a mixture (1:1) of 1-octadecene and oleylamine with H2N-(CH2)3-SePh dissolved in ...
