4-Chlorophenol → 1-Chloro-4-[(5,5-dichloro-3,3-dimethylpent-4-en-1-yl)oxy]benzene

Participants

Reaction Steps

128 g (1 mol) of 4-chlorophenol, 201 g (1 mol) of 1,1,5-trichloro-3,3-dimethyl-1-pentene (II) and 138 g (1 mol) of potassium carbonate in 1 liter of diethylene glycol dimethyl ether are heated under reflux for 10 hours. The mixture is then diluted with methylene chloride and extracted by shaking several times with water. The organic phase is freed of solvent on a rotary evaporator and then distilled at a boiling point of 135°-140° C./0.1 mbar. 252 g (0.86 mol, which is 86% of theory) of 5-(4-chlorophenoxy)-1,1-dichloro-3,3-dimethyl-1-pentene are obtained.
