A novel soluble compound which is a distyrylarylene derivative having a soluble substituent and a specific central group and having a solubility of 0.5% by weight or greater at 20°C in an organic solvent; and an organic electroluminescence device having an organic thin film layer which has a single layer or a plurality of layers, is disposed between a cathode and an anode and has at least one layer containing the novel soluble compound. The organic thin film layer can be formed in accordance with a wet process, and the organic electroluminescence device exhibiting a great efficiency of light emission can be produced easily.

The oxidation of 2-methyl-5-tert-butyldiphenylmethane and its 4'-methyl-, chloro-, and nitro-substituded derivatives by potassium permangate in a mixture of pyridine and water leads to the formation of the correspoding 2-benzoyl-4-tert-butyl-benzoic acids, which are converted by the action of sulfuric acid with heat into substituted 2-tert-butylanthraquinones.The cyclization of 2-benzoyl-4-tert-butylbenzoic acids containig a tert-butyl group or chlorine atom in the benzoyl ring is accompanied by a Hayashi rearrangement, which leads to the formation of mixtures thecorresponding 2,6- and 2,7-disubstituted anthraquinones.
