一般說明

四氢呋喃(THF)是一种饱和环醚,主要用作有机溶剂。长期储存时,它会形成有机过氧化物。可通过添加丁基羟基甲苯(BHT)作为稳定剂而抑制这一过程。BHT能去除形成过氧化物所需的自由基。它是各种天然产物(聚醚类抗生素)的关键片段。THF可与硫化氢形成双水合物,其晶体结构已经过三维单晶研究法进行过研究。

應用

干燥四氢呋喃(THF)已用于合成二氯{双[1,1′,1′′-(膦三基)三哌啶]钯[(P(NC5H10)3)2Pd(Cl)2],广泛用作Heck反应中的催化剂。它已被用于各种芳基溴和烯烃的Heck交叉偶联反应介质。

其他說明

2-甲基四氢呋喃(414247)和环戊基甲基醚(675970)是许多THF应用更环保的替代选择。
