Carbon Dioxide → 4-Vinylphenol

Participants

Reaction Steps

The reaction is based on that described by Corson et al. J Org Chem (1958) 544–549; molar ratios acetoxystyrene:base 1:1.5. The base, KOH in water (30%) was immersed in an ice bath and the acetoxystyrene was added dropwise over 30 mins (all reaction carried under N2; the reaction was TLC monitored (20–80 cyclohexane-dichloromethane) until all acetoxystyrene disappeared, then the pH was brought down to 8 with CO2; the resulting precipitate was filtered and washed with water, then recrystallised from boiling hexane and NMR characterised.
