Abstract 9-Fluorenyl carbocations substituted with the oxime functional groups CH [DOUBLE BOND] NOCH 3, CH 3 C [DOUBLE BOND] NOCH 3, and i-PrC [DOUBLE BOND] NOCH 3 were generated by solvolyses of the corresponding chlorides in methanol. These cations form at rates which greatly exceed those of formation of the parent 9-fluorenyl cation. Relative rate data suggest that stabilization of 9-fluorenyl cations by CH [DOUBLE BOND] ...
