A general method for the synthesis of five-membered and six-membered selenaheterocycles through Ag-catalyzed C?Se bond-forming reaction is reported. This reaction proceeds via intramolecular cyclization of arylboronic acids with selenium powder. Preliminary mechanism studies demonstrate that this transformation involves a selenium-centred radical intermediate. (Figure presented.).

By using vicinal trifluoromethanesulfonate-substituted diaryliodonium salts, a novel approach was developed for the synthesis of ortho-iodo diaryl ethers by intramolecular aryl migration. The reaction conditions are mild with a broad substrate scope. Mechanistic insight suggests a sulfonyl-directed nucleophilic aromatic substitution pathway. Additionally, the product ortho-iodo diaryl ethers serve as versatile synthons as demonstrated with several coupling reactions. Furthermore, a useful thyroxine analogue of the 3-iodo-l-thyronine (3-T1) derivative was synthesized by this aryl migration procedure.

The invention provides an anthracene compound. The anthracene compound has a structure in the formula (I), wherein Q is the C1-60 alkyl group or the C6-60 aryl group or the C5-60 condensed ring group or the C5-60 heterocyclic group; Ar is the C6-60 aryl group or the C5-60 condensed ring group or the C5-60 heterocyclic group; and Ar1 is H, the C1-60 alkyl group, the C1-60 alkoxy group, the C1-60 ether group, the C6-60 aryl group, the C6-60 condensed ring group, the C6-60 heterocyclic group and the C6-60 arylamine group. Compared with the prior art, the anthracene compound is connected with an aromatic compound through anthracene, and the Q, Ar and Ar1 groups are introduced, so that a device emits blue light after the organic compound is applied to the organic light-emitting device; and meanwhile, the means that the above groups are used for adjusting the light-emitting wavelength is adopted, the light-emitting efficiency of the organic light-emitting device is high, and the service life is long.
