Sodium Bicarbonate → 1-(Isopropylsulfanyl)-2-vinylbenzene

Participants

Reaction Steps

Methyl triphenylphosphonium iodide (1.57 g, 3.88 mmol) was dissolved in 25 mL ether in a 50 mL round-bottomed flask at 0° C. under dry nitrogen. To the mixture was added in one portion potassium tert-butoxide (0.47 g, 4.16 mmol) and it was stirred for 10 min at room temperature. 2-(isopropylsulfanyl)benzenecarbaldehyde (0.50 g, 2.77 mmol) was added in one portion at 0° C. and the reaction mixture was stirred for additional 24 h at room temperature. The mixture was added to 50 mL of saturated sodium bicarbonate solution, and then was extracted with 3×50 mL portions of ether. The extracts were dried with magnesium sulfate and evaporated. The light yellow oil of the crude product was further purified by chromatography on silica gel using 95:5 petroleum ether 60-80 and ether as eluent to give a colorless oil (0.40 g, 81%).
