Versuchsvorschrift
3-Decyloxythiophene was synthesized as follows. 1-Decanol (0.51 mol, 80.27 g) was added dropwise to 3.5 g (0.15 mol) of sodium metal. After complete disappearance of sodium, the residual alcohol was removed in vacuum and the remaining solid was dissolved in 20˜30 ml DMF. After the solution was heated to 110° C., 12.2 g (0.075 mol) of 3-bromo-thiophene and 1.0 g (0.00053 mol) of copper (I) iodide were added. After 16 hrs of stirring at 110° C., the mixture was poured into water and extracted with ether three times. The filtrate was concentrated in vacuo and the yellow oily residue was chromatographed on a silica column using hexane as the eluent to yield 15.5 g of yellow liquid (86% yield). Mw=240.4. Element Anal. Calcd for C14H24SO: C, 69.94; H, 10.06; 0, 6.66; S, 13.34. Found: C, 69.90; H, 10.00; 0, 6.64; S, 13.30.
