Acetone → 1-Fluoro-4-(prop-2-en-1-yloxy)benzene

Participants

Reaction Steps

A mixture of 336.3 parts of 4-fluorophenol, 417.5 parts of allyl bromide, 420 parts of potassium carbonate and 480 parts of acetone is stirred and refluxed for 8 hours. After cooling to room temperature, 2250 parts of water are added. The aqueous layer is separated and extracted twice with ether. The combined extracts are washed successively twice with sodium hydroxide solution 10% and twice with sodium chloride solution, dried over potassium carbonate, filtered and evaporated. The oil residue is distilled in vacuo, yielding 381.8 parts of 4-allyloxy-fluorobenzene; bp. 93° C at 23 mm. pressure; nD20 : 1.4950;d2020 : 1.070.
