一般描述

N, N-二甲基甲酰胺(DMF)是一种有机化合物,在有机合成中常用作试剂和溶剂。它在各种反应中起着多重作用,如甲酰化剂、脱水剂、还原剂以及催化剂。

应用

DMF 可用作:     
  • 有机金属化合物的甲酰化剂。
  • 反应物,通过与氯化氧磷的反应制备 Vilsmeier 试剂。
  • 试剂,在叔丁醇钾环境下进行芳酰氯的胺化。     
  • 金属盐的还原剂,用于制备金属胶体。
  • 催化剂,用于无保护碳水化合物的区域选择性硅基化。

DMF 还可用于以下用途:     
  • DMF-光气催化体系用于从乙醇制备烷基卤化物。      
  • DMF-POCl3 用于将无环和环烯化酮转化为 β-氯-α, β-不饱和醛。
  • DMF-POCl3 用于从酰基苯胺合成喹啉-3-羧基。      
  • DMF-SOCl2 混合物用于将氧脱水成腈。      
  • DMF-Ag2O 将 α-溴丙酰胺转化为恶唑烷酮。
  • DMF 在许多要求高溶解力的化学反应中经常用作溶剂。

多种疏水性有机化合物的溶剂。
