Краткое описание
A series of 9-substituted 9-fluorenyl cation were prepared and characterized by 1 H and 13 C NMR spectroscopy. Unsuccessful attempts were made to observe intramolecular interconversion of 9-methyl-9-fluorenyl cation via capped pyramidal ions with ring deuterated and methylated analogues. MINDO/3 calculations on isomeric structures of cyclopentadienyl, indenyl, and fluorenyl cations indicated strongly decreasing relative stabilities of the pyramidal forms due to benzoannulation. In deuterated fluorosulfonic acid solution, the 9-methyl-9-fluorenyl (1-CH 3 ) and 3.9-dimethyl-9-fluorenyl cations (14) underwent hydrogen-deuterium exchange consistent with a protonation-deprotonation mechanism.
