실험 절차

Methyl triphenylphosphonium iodide (1.57 g, 3.88 mmol) was dissolved in 25 ml ether in a 50 mL round-bottomed flask under dry nitrogen. To the mixture was added in one portion at 0° C. potassium tert-butoxide (0.47 g, 4.19 mmol) and it was stirred for 10 min at room temperature. 2-(tert-butylsulfanyl)benzenecarbaldehyde (2.77 mmol) was added in one portion at 0° C. and the reaction mixture was stirred until complete disappearance of the reactants (24 hr) at room temperature (followed by TLC). The mixture was added to 50 mL of saturated sodium bicarbonate solution, followed by extraction with 3×50 ml portions of ether. The extracts were dried with magnesium sulfate and evaporated. The crude product was further purified by chromatography on silica gel using petroleum ether 60-80 as eluent. 0.37 g, 70%, colorless oil. 1H NMR (200 MHz, CDCl3): δ 1.26 (s, 9H), 5.28 (dd, J1=11.0, J2=1.2, 1H), 5.68 (dd, J1=17.8, J2=1.2, 1H), 7.17-7.67 (m, 5H) ppm.
