HCID 170249ar-Vinylbenzyl chloride

実験手順

3-Ethenylbenzyl alcohol (5.26 g) was dissolved in carbon tetrachloride (100 ml) and triphenylphosphine (10.2 g) added. The solution was refluxed overnight and then left to cool. A white precipitate formed which was filtered through celite. The filtrate was evaporated in vacuo to yield a crude product. The residue was purified by gravity chromatography on silica using 5% dichloromethane in petrol (60-80) as eluant. This yielded the pure product.
