実験手順: Dissolve 1-chloromethyl-2-vinyl-benzene (4.0 g, 26 mmol) in acetone (100 mL) and add sodium iodide (4.5 g, 30 mmol). Heat at gentle reflux for 30 minutes. Cool, add water (150 mL) and extract with pentane (200 mL). Dry (MgSO4) and evaporate the solvent in vacuo to give the title compound (95%). Heat at gentle reflux for 30 minutes Cool extract with pentane (200 mL) Dry (MgSO4) evaporate the solvent in vacuo

反応条件: temp:-35.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: Dissolve methanesulfonic acid 2-(2-chloromethyl-phenyl)-ethyl ester (8.8 g, 35.4 mmol) in ether (80 mL) and cool to -35° C. Add potassium t-butoxide (10 g, 89 mmol) and stir for 30 minutes. Add water (50 mL) and ether (150 mL), extract, dry (Na2SO4) and purify by silica gel chromatography (2:3 methylene chloride/pentane) to give 1-chloromethyl-2-vinyl-benzene as a colorless oil (4.43 g, 82%). Add water (50 mL) and ether (150 mL), extract dry (Na2SO4) purify by silica gel chromatography (2:3 methylene chloride/pentane)

実験手順: Finally the art teaches in U.S. Pat. No. 2,780,604 that chloromethyl vinyl benzene can be prepared via a two step liquid phase reaction whereby isopropyl toluene is chlorinated via ultraviolent light and the subsequently distilled chloromethyl chloroisopropyl benzene is dehydrohalogenated with heat to give chloromethylisopropenylbenzene. with heat
