The present disclosure relates to an emitting compound and organic light emitting device including the same, and more specifically, relates to an emitting compound of following and an organic light emitting diode and an organic light emitting device each including the emitting compound. ##STR00001##

The present invention addresses the problem of providing a solid catalyst capable of achieving high selectivity and high yield for isosorbide, preferably at the same time, in a dehydration reaction by which dianhydrosugar alcohol is obtained from a sugar alcohol, particularly, in a dehydration reaction by which isosorbide is obtained from sorbitol. The above-mentioned problem is solved by a solid catalyst for a dehydration reaction for preparing dianhydrosugar alcohol from sugar alcohol, said catalyst including an H-type zeolite having an atomic composition ratio of Si to Al (Si/Al) of more than 20.

An oxidation catalyst includes a nickel-containing material, a manganese-containing material and a bromine-containing material, wherein the molar number of the element bromine (Br) in the oxidation catalyst to the total molar number of the element nickel (Ni) and the element manganese (Mn) in the oxidation catalyst substantially ranges from 0.01 to 7.5.

The present invention provides compositions and methods for the selective CH fluorination of nitrogen-containing heteroarenes with AgF.sub.2, which has previously been considered too reactive for practical, selective CH fluorination. Fluorinated heteroarenes are prevalent in numerous pharmaceuticals, agrochemicals and materials. However, the reactions used to introduce fluorine into these molecules require pre-functionalized substrates or the use of F.sub.2 gas. The present invention provides a mild and general method for the CH fluorination of nitrogen-containing heteroarene compounds to 2-fluoro-heteroarenes with commercially available AgF.sub.2. In various embodiments, these reactions occur at ambient temperature within one hour and occur with exclusive selectivity for fluorination at the 2-position. Exemplary reaction conditions are effective for fluorinating diazine heteroarenes to form a single fluorinated isomer.
