Mass spectroscopic study of compounds from the cyclopropane series 6. Behavior of alkyl and aryloxy gem-dichlorocyclopropanes under chemical ionization

Chemical ionization mass spectra have many advantages over electron impact mass spectra in studying the alkyl and aryloxy gem-dichlorocyclopropanes. Most of these compounds gives highly stable quasimolecular ions and the products obtained from decomposition of the latter furnish more complete information concerning molecular structures.
