Abstract:  Preparation of halo and nitro derivatives of 3-naphthyloxymethylenephthalides by Gabriel modification of Perkin synthesis from phthalic anhydride and the properly substituted naphthyloxyacetic acid as well as by nitration and halogenation of unsubstituted E and Z isomers of 3-naphthyloxymethylenephthalides is dealt with. Some of the prepared derivatives have been proved to inhibit plant growth.
