实验过程

6-Methoxy-naphthaldehyde (432 mg, 2.35 mmol) is added to a solution of instantaneous ylide (Ph3P+Br−+NaNH2, 1.48 g, 2.4 mmol) in anhydrous THF (5 ml). After one hour of stirring at ambient temperature, it is diluted with ether, it is filtered on Celite, and it is chromatographed (hexane/AcOEt 5:1) to obtain 6-methoxy-2-vinyl-naphthalene (390 mg, 90%).
