-

Yield:94-59-7 80%

Reaction Conditions:

with Nafion-H resin at 20;Friedel-Crafts Alkylation;

Steps:

General procedure
Nafion-H (14.65 g, 10 % wt. % based on the 1,2-methylene-dioxybenzene was used) was added to the mixture of 1,2-methylenedioxybenzene (146.54 g, 1.2 mol) and allyl alcohol (2.33 g, 0.04 mol) and stirred at room temperature until the allyl alcohol is disappeared. The Nafion-H catalyst was filtered off. Excess 1,2-methylenedioxybenzene was removed under reduced pressure. The crude product was vacuum distilled, 5.19 g of safrole, boiling at 120-130 °C (10-15 mm Hg), was obtained. Colourless and typically smelling oil. Total yield (from the allyl alcohol), 80 % of theory.
