Versuchsvorschrift

Woods et al. (U.S. Pat. No. 5,019,629) describe a two-step procedure for preparing p-(2-hydroxyethoxy)styrene starting with p-hydroxybenzaldehyde. In the first step, p-(2-hydroxyethoxy)benzaldehyde is formed by reacting p-hydroxybenzaldehyde with ethylene carbonate in the presence of potassium carbonate. In the second step, p-(2-hydroxyethoxy)styrene is formed by reacting the isolated p-(2-hydroxyethoxy)benzaldehyde with methyltriphenylphosphonium bromide in the presence of sodium amide.
