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.

Epoxidation of Barrelene: Preparation and Properties of Oxahomobarrelenes

A four-step synthesis makes barrelene (1) readily accessible on a 1-2 g scale.Upon epoxidation with KHCO3-buffered m-chloroperbenzoic acid 1 yields the mono- (2b), both the endo,exo- and exo,exo-isomeric bis- (3b and 4b) as well as the trisepoxide 5b.In the presence of traces of acid 2b very rapidly rearranges to cycloheptatriene-7-carbaldehyde (15), 5b undergoes a facile acid-catalyzed rearrangement to 4,7,11-trioxatrishomocubane (16).Under basic and neutral conditions 5b is stable towards virtually any nucleophile, its three epoxide rings can only be opened underreductive conditions with solvated electrons.On the other hand, endo,exo-dioxadihydrobishomobarrelene 20 and oxatrishomobarrelene 23 are readily attacked at the oxirane rings by lithium iodide/disodium hydrogen phosphate.
