2,2′:5′,2″-四噻吩-5-甲醛的合成与表征
The Synthesis and Characterization of the 5 - Formy1- 2,2′ : 5 ′ ,2"- Terthiophene
摘要
Abstract
The reaction was carried out through Vilsmeier-reaction with the 2,2': 5' ,2" - terthiophene as raw material, in which the electrophilic reagent was synthesized in the temperature of nearby zero degrees centigrade with POC13 as condensating agent and DMF as formylating agent, then the H in the position of a of 2,2 :5 ,2 -terthiophene was substituted by the electrophilic reagent, the 5 - formyl- 2, 2': 5', 2" - terthiophene was obtained via basic hydrolysis (pH = 8), of which the higher purity quotient was obtained through silica flash chromatography with the productive rate of 84. 97%. It's structure was characterized and analyzed using FT-IR,UV-vis, 1H - NMR, and the melting point and boiling point was measured and analyzed by DSC, which is in agreement with the literature.关键词
