- NOVEL TRIAZINE COMPOUND, AND ORGANIC ELECTRONIC ELEMENT AND PLANT-GROWING LIGHTING THAT USE THE SAME
-
PROBLEM TO BE SOLVED: To provide a triazine compound which has a high triplet energy level and excellent heat resistance, and can be used as an organic electronic element material realizing an element with high efficiency, low voltage and a long life. SOLUTION: In the triazine compound, as represented by the general formula [1] in the figure, a triazine backbone moiety is linked to a dibenzofuran or dibenzothiophene backbone moiety via a biphenyl backbone moiety, where X is an oxygen atom or sulfur atom.

- Synthesis of diaryl ethers, diaryl thioethers, and diarylamines mediated by potassium fluoride-alumina and 18-crown-6: Expansion of scope and utility
-
An efficient alternative to the Ullmann ether synthesis of diaryl ethers, diaryl thioethers, and diarylamines involving the S(N)Ar addition of a phenol, thiophenol, or aniline to an appropriate aryl halide, mediated by potassium-fluoride alumina and 18-crown-6 in acetonitrile or DMSO, is described. Expansion of the reaction conditions to include DMSO as solvent has resulted in a far greater range of substitution patterns permitted on the electrophile. For example, it was found that electronically unfavorable 3- chlorobenzonitrile could be condensed with 3-methoxyphenol to form the corresponding diaryl ether in 66% yield, a combination not normally amenable to Ullmann coupling. Electron-withdrawing groups present on the electrophile may be as diverse as nitro, cyano, formyl, acetyl, ester, amide, and even aryl. The method features a simple reaction procedure that provides products in generally good to excellent purified yields.
