Abstrakt: Conclusions 1.1-Phthaloyl-2-p-X-substituted benzoylcyclopropanes (where X=F, Cl, Br, OCH3), regardless of the substituent, are selectively reduced by ionic hydrogenation to 1-phthaloyl-2-p-substituted benzylcyclopropanes. As the electronegativity of the substituent decreases, the reduction rate increases.2.The stability of the phthaloyl CO groups and the three-membered ring in this reaction is attributed to their mutual interaction; this agrees well with experimental data and with the13C NMR spectra of the compounds.
