Paragraph 0149; 0164; 0300-0302, (2016/10/10)
The present invention relates to an organic light emitting compound applied to an organic electroluminescent device. The organic light emitting compound is represented by chemical formula 1 or chemical formula 2. The organic electroluminescent device having excellent light emitting properties such as driving voltage, luminance, and long lifespan can be implemented in the case of using the organic light emitting compound as a host compound inside a light emitting layer.COPYRIGHT KIPO 2016

Simple and efficient synthetic procedures for the selective preparation of 3-bromo/3-chloroindoles and 2,3-dibromo/2,3-dichloroindoles by using 1,3-dibromo-5,5-dimethylhydantoin (DBDMH) and 1,3-dichloro-5,5-dimethylhydantoin (DCDMH) were developed. Using 1,4-dioxane as the solvent, a variety of indoles, treated with 0.55 equiv DBDMH/DCDMH, afford the corresponding 3-bromo/3-chloroindoles selectively in 82-99% yield. In 1,2-dichloroethane (DCE), a series of 2,3-dichloro/2,3-dibromoindoles were selectively obtained in 84-95% yield by treating with DBDMH/DCDMH. All the processes do not need extra catalysts, dry solvents, or harsh reaction conditions.
