1、---------------------------------------------------------------范文最新推薦------------------------------------------------------取代苯異腈與芳胺的加成反應(yīng)摘要:脒是氮取代的羧酸類似物,脒類化合物是重要的有機(jī)合成中間體,在農(nóng)藥和醫(yī)學(xué)等方面有著廣泛的應(yīng)用。本課題論文主要探究一系列芳香族伯胺和仲胺對(duì)氯代甲酰苯胺和N-(4-(3-三氟甲基-4-氯)苯氧基)甲酰苯胺對(duì)應(yīng)的異腈的親核加成反應(yīng)。首先利用氯代苯胺與甲酸發(fā)生甲?;磻?yīng)生成相應(yīng)的氯代甲酰苯胺,再以二
2、甲苯作為溶劑,用三乙胺來提供堿性環(huán)境,以POCl3為脫水劑,使取代甲酰苯胺和N-(4-(3-三氟甲基-4-氯)苯氧基)甲酰苯胺分別脫水生成對(duì)應(yīng)的中間體異腈,之后加入催化劑Cu2O和芳香族胺得到產(chǎn)物脒。通過1H譜分析產(chǎn)物的純度以及產(chǎn)率,從而得出該方法在芳香族類化合物的合適反應(yīng)范圍。9691關(guān)鍵字:脒;取代苯異腈;芳香胺;合成Substitutedbenzylisonitrileadditionreaction11/11---------------------------------------------------------------范文最新推薦-----
