4-Chlorophenol → HCID 53948317, compound

Participants

Reaction Steps

51.4 g (0.4 mol) of p-chlorophenol are reacted, in 300 ml of dimethylformamide, with 80 ml of 30% strength sodium methylate solution (0.4 mol), and the solvent is then stripped off at 30 mbar. 33 g (0.2 mol) of 1,1-dichloro-3,3-dimethyl-1,4-pentadiene are then added to the mixture, and the latter is heated under reflux during the course of 9 hours. The working-up is according to Example A1(a). The distillation at a boiling point of 122°-130° C./0.2 mm Hg yields 44.8 g of 1-chloro-3,3-dimethyl-2-(p-chlorophenoxy)-1,4-pentadiene, which are 87% of theory.
