- 中文摘要: Seventeen 1-arly-2,2-dichlorocyclopropanes were examined by using IR, /sup 13/C NMR and mass spectrometry. The data obtained from IR and /sup 13/C NMR spectra indicate that the bond strength of carbonchlorine on the cyclopropane ring and the electron density of that carbon depend on the substituent. The mass fragmentation patterns of compounds in this series resemble those of the dibromo analogues. The fragmentation mechanism is proposed to involve the formation of indenium ion through an electrocyclization.
