(Bromodichloromethyl)phenylmercury → Methyl 3-(4-chlorophenoxy)-2,2-dichlorocyclopropanecarboxylate

Participants

Reaction Steps

A mixture of methyl 3-(4-chlorophenoxy)-2-propenoate (30 mmol), phenyl(bromodichloromethyl)mercury (30 mmol) and 50 ml benzene are heated under reflux, with stirring, for 4 hr, followed by TLC of the product. The mixture is then filtered and the solvent removed, giving methyl 3-(4-chlorophenoxy)-2,2-dichlorocyclopropanecarboxylate, which is then hydrolyzed and reacted with m-phenoxybenzyl bromide to give m-phenoxybenzyl 3-(4-chlorophenoxy)-2,2-dichlorocyclopropanecarboxylate.
