Tetrahydrofuran(THF)

Dangerous Goods

CAS number:109-99-9    molecular formula:C4H8O

overview

compound introduction

有醚样气味。能与水、醇类、醚类、酮类、酯类和烃类混溶。易燃。有刺激性。 氨基酸和肽的纸层析。溶剂。有机合成。高效液相色谱,紫外发光光度分析。 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。 应用: 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。 Tetrahydrofuran (THF) is a saturated cyclic ether that is mainly used as an organic solvent. When stored for a long time, it forms organic peroxides. This process can be inhibited by adding butylhydroxytoluene (BHT) as a stabilizer. BHT removes free radicals needed to form peroxides. It is a key fragment of various natural products (polyether antibiotics). THF can form double hydrates with hydrogen sulfide, and its crystal structure has been studied by three-dimensional single crystal method. Application: Dried tetrahydrofuran (THF) has been used to synthesize dichloride {bis [1,1 ',1 "-(phosphine triyl) tripiperidine] palladium [(P(NC5H10)3)2Pd(Cl)2], which is widely used as a catalyst in Heck reactions. It has been used as a Heck cross-coupling reaction medium for various aryl bromine and olefin.
