Dodecahedryl cation

Starting with dodecahedrane or substituted derivatives, Olah, Prakash, Paquette, and coworkers prepared dodecahedryl cation 59 under superacid conditions193,194... [Pg.119]

Olah and coworkers also prepared the parent dodecahedryl cation 29 under superacid conditions [Eq. (6.20)]. Upon standing in the superacid medium at -50°C, it slowly and irreversibly transformed into 1,16-dodecahedryl dication 31. The formation of dication 31 can be rationalized by protolytic ionization of the C-H bond at C(16) farthest from the cation center presumably involving hypercarbon intermediate 30. [Pg.312]

The cationic centers of the dodecahedryl mono- and dications (8 C 363.9 and 379.2, respectively) are the most deshielded absorptions yet observed for any... [Pg.242]
