Reactions of 2- and 3-Phenyl Substituted Alkylalkylidene Iminium Ions in the Gas Phase

Article abstract of DOI:10.1002/hlca.19810640413

The collision-induced fragmentations of 2- and 3-phenyl substituted alkylalkylidene iminium ions are reported.Besides the homolytic cleavage of the aza-allyl bond a nucleophilic attack of the unsubstituted phenyl group at the iminium function is observed in the gas phase, yielding carbonium ions such as cyclopropan-spirobenzenium (3), indanylium (10) and indenylium ions (11).
