The cyclisation conditions for the formation of bicyclo[2.2.2]octan-2,6-di one (1) from 3-substituted cyclohexanones 2 and 3 have been re-investigated. Use of a medium consisting of isobutyric anhydride and trifluoroacetic acid resulted in a simplified and reproducible method for large-scale synthesis of this compound.

A subject for the invention is to provide compounds where a film formation can be made by a wet film formation method, a heating temperature at the film formation is low, the film formed therefrom has high stability, and the other layers can be laminated thereon by a wet film formation method or another method. The compounds are usable as a material for electronic device which decreases little in charge transport efficiency or luminescent efficiency and which have excellent driving stability. The invention resides in a compound and a polymer which are characterized by having a elimination group of a specific structure and in an organic compound characterized by having a elimination group having a low elimination temperature.
