Ethylene Glycol → 2-(Thiophen-3-yloxy)-ethanol

참여 물질

반응 조건

반응 단계

To a solution of 1.0 g (4.76 mmol) 3-iodothiophene in 5 ml ethylene glycol is added 109 mg (1.71 mmol) copper powder, 114 mg (0.714 mmol) copper(II)sulphate and 151 mg (19.0 mmol) lithium hydride. The reaction mixture is heated overnight in a sealed flask at 100° C. The reaction mixture is filtered through Celite and evaporated. The resulting oil is then filtered through a 50 g silica pad and eluted with ethyl acetate/hexanes (7:3) to give after evaporation 750 mg of an orange liquid, which is used without purification directly in the next reaction.
