Reaction Conditions:
with fluorosulfonyl fluoride;potassium tert-butylate in dimethyl sulfoxide at 60;
Steps:
2 Example 2
In a 100mL reaction flask, add 1.72g 1-naphthylethanol (10mmol), 50mL dimethylsulfoxide, 5.6g potassium tert-butoxide (50mmol), plug the rubber stopper, stir at 60°C, and pass the sulfuryl fluoride balloon through the long The needle is passed into the reaction solution, and another short needle is inserted into the rubber stopper to make the sulfuryl fluoride in the balloon flow with the air in the reaction system. After 5 minutes, the short needle is pulled out, and the reaction system is reacted in a 60C oil bath. -15 hours. The progress of the reaction was checked by a thin-layer chromatography plate. After the reaction, the reaction solution was extracted with water and dichloromethane (3 X 20 mL). The dichloromethane layer was dried over anhydrous sodium sulfate, filtered, and spin-dried. The residue was applied to a silica gel column. Analytical purification, the eluent is pure petroleum ether, that is, 1-naphthalene ethylene (1.36g, 88%)
