Base-mediated intermolecular sp2 C-H bond arylation via benzyne intermediates

A transition-metal-free method for arylation of heterocycle and arene carbon-hydrogen bonds by aryl chlorides and fluorides has been developed. The reactions proceed via aryne intermediates and are highly regioselective with respect to the C-H bond coupling component.

Organometallic Complex, and Light-Emitting Element, Light-Emitting Device, and Electronic Device Using the Organometallic Complex

According to the present invention, a wider variation of organometallic complexes that can emit phosphorescence can be provided by applying, as a ligand, an organic compound from which a variety of derivatives can be easily synthesized. In particular, an organometallic complex having a sharp emission spectrum is provided. Further, an organometallic complex having high emission efficiency is provided. An organometallic complex represented by the general formula (G1) is provided. In the formula, Ar represents an aryl group, R represents an alkoxy group having 1 to 4 carbon atoms, and R1 and R2 individually represent either hydrogen or an alkyl group having 1 to 4 carbon atoms.

Studies on Pyrazines. Part 27. A New Deoxidative Nucleophilic Substitution of Pyrazine N-Oxides; Synthesis of Azidopyrazines with Trimethylsilyl Azide

Azidopyrazines bearing amino, methoxy and/or phenylgroups have been synthesized by reaction of pyrazine N-oxides with trimethylsilyl azide in the presence of diethylcarbamoyl chloride in refluxing acetonitrile.In most cases, the azidation occurs only at t
