Copper-Catalyzed Coupling of Arylboronic Acids and Amines
摘要:
[GRAPHICS]A general catalytic coupling of arylboronic acids and amines is reported. This room-temperature coupling was realized through the use of catalytic copper(II) acetate, 2,6-lutidine as base, and myristic acid as an additive. Functionalized aniline substrates provided the diarylamine coupling products in good yield (58-91%), A variety of alkylamines were also successfully coupled to give N-alkyl anilines in moderate yield (50-64%).

(DiMeIHeptCl)Pd, a hyper-branched N-aryl Pd NHC catalyst, has been shown to be efficient at performing amine arylation reactions in solvent-free (“melt”) conditions. The highly lipophilic environment of the alkyl chains flanking the Pd center serves as lubricant to allow the complex to navigate through the paste-like environment of these mixtures. The protocol can be used on a multi-gram scale to make
An electroluminescence device having an emission layer comprising a single organic compound layer between a cathode and an anode. The single layer may comprise an emitter component on a single polymer chain of covalently linked (co)-polymer sections Y1, optionally in combination with Y2, and/or Y3, or different polymer chains Y1, optionally in combination with Y2, and/or Y3 blended together. Each of the (co)-polymer contains a spacer unit and a carrier transporting component and optionally an emitter moiety.
