Acetic Acid → 4-(2,6-Dichloro-4-(3,3-dichloro-2-propenyloxy)phenoxy)butyloxyacetaldehyde

Participants

Reaction Steps

Then, 1.81 g of 3,5-dichloro-1-(3,3-dichloro-2-propenyloxy)-4-(4-(2,2-diethoxyethoxy)butyloxy)benzene was added to a mixture of 10 ml of acetic acid and 1 ml of concentrated hydrochloric acid with stirring under ice cooling, and the stirring was further continued for 15 minutes. The reaction mixture was poured into water, and extracted twice with diethyl ether. The diethyl ether layers were combined, washed with water, saturated aqueous sodium hydrogencarbonate solution, and saturated aqueous sodium chloride solution in this order, dried over anhydrous magnesium sulfate, and concentrated, which afforded 1.51 g (yield, 94%) of 4-(2,6-dichloro-4-(3,3-dichloro-2-propenyloxy)phenoxy)butyloxyacetaldehyde.
