Paragraph 0091-0094; 0161-0165, (2020/12/14)
An organic electroluminescent device includes a monoamine derivative represented by Formula 1: In Formula 1, Ar1 may be represented by Formula 2; Ar2 may be a substituted or unsubstituted aryl group having 6 to 30 carbon atoms for forming a ring, wherein the substituent of Ar2 is an unsubstituted aryl group having 6 to 30 carbon atoms for forming a ring; Ar1 and Ar2 may be different from each other; m may be an integer from 0 to 4; and R1 may be a substituted or unsubstituted aryl group having 6 to 30 carbon atoms for forming a ring, and when m is 2 or more, a plurality of R1 may combine to form a ring:

The Br?nsted acid-catalyzed synthesis of primary amines from acetyl arenes and alkanes with C-C bond cleavage is described. Although the conversion from an acetyl group to amine has traditionally required multiple steps, the method described herein, which uses an oxime reagent as an amino group source, achieves the transformation directly via domino transoximation/Beckmann rearrangement/Pinner reaction. The method was also applied to the synthesis of γ-aminobutyric acids, such as baclophen and rolipram.
Direct conversion of phenols into primary anilines with hydrazine catalyzed by palladium

Primary anilines are essential building blocks to synthesize various pharmaceuticals, agrochemicals, pigments, electronic materials, and others. To date, the syntheses of primary anilines mostly rely on the reduction of nitroarenes or the transition-metal-catalyzed Ullmann, Buchwald-Hartwig and Chan-Lam cross-coupling reactions with ammonia, in which non-renewable petroleum-based chemicals are typically used as feedstocks via multiple step syntheses. A long-standing scientific challenge is to synthesize various primary anilines directly from renewable sources. Herein, we report a general method to directly convert a broad range of phenols into the corresponding primary anilines with the cheap and widely available hydrazine as both amine and hydride sources with simple Pd/C as the catalyst.
