4‘-diamine 2g shows significant differences in the torsion angle between the naphthalene moieties depending on its oxidation state. Twisted structures are preferred for neutral compounds, whereas more planar are favored for the oxidized forms 2g•+ and 2g2.2+ to realize spin and/or charge delocalizations over the whole π-system. Such conformation changes concerted with the electron transfers contribute to explain

catalyzed Buchwald–Hartwigamination reactions, because of its broad scope and high probability of success. It does not, however, work well with unactivated arylchlorides. Herein NIXANTPHOS is compared to Xantphos and an array of mono- and bidentate phosphines. NIXANTPHOS outperforms Xantphos and all other bidentate ligands examined. Under the optimal reaction conditions, unactivated arylchlorides afford

Oxidative clicklike reactions are useful for the late-stage functionalization of pharmaceuticals and organic materials. Hence, novel methodologies that enable such transformations are in high demand. Herein we describe a tellurium(II)-catalyzed cross-dehydrogenative phenothiazination (CDP) of aromaticamines. A key feature of this method is a cooperative effect between the phenotellurazine catalyst

A compound represented by Formula 1. An organic electric element includes a first electrode, a second electrode, and an organic material layer including the compound of Formula 1. The organic material layer include a light emitting layer, a hole transport layer including a compound represented by Formula 2, and an emission-auxiliary layer including the compound represented by Formula 1. When the organic electric element includes the compound in the organic material layer, luminous efficiency, color purity, and life span can be improved.
