Transition Metal Free Homocoupling of Unactivated Electron Deficient Azaarenes

This work has established the first direct homocoupling of unactivated electron deficient azaarenes in the presence of TMPMgCl (2,2,6,6 tetramethylpiperidinylmagnesium chloride) and TMEDA (tetramethylethylenediamine). In this process, no transition metal was used while freely available air was employed as the oxidant. The investigated successful substrates included quinolines, isoquinoline, 3 phenylated pyridines, and 2 phenylated quinoxalines, giving moderate to high yields. The homocoupling of quinolines was effectively scaled up to one gram in high yield. Additionally, an iridium complex of 6,6′ dimethyl 2,2′ biquinoline was prepared and characterized as an efficient red emitting material.

Method for preparing symmetric dimer of nitrogen heterocyclic ring aromatic compound

The invention discloses a method for preparing a symmetric dimer of a nitrogen heterocyclic ring aromatic compound, a product prepared by the method and application of the product. The method comprises the following steps: adding a solvent in which a Grignard reagent is dissolved into a reaction container under protection of an inert gas, and slowly dropwise adding secondary amine into the Grignard reagent solution; then, adding a second kind of solvent into the reaction container to dissolve the product obtained in the reaction of the Grignard reagent and the secondary amine, adding a nitrogen complex reagent into the mixture, complexing, and adding a nitrogen heterocyclic ring aromatic compound to react at 20-200 DEG C; and quenching the reaction after the reaction is completed, and oxidizing the reaction product with air or oxygen to transform the reaction product into the symmetric dimer of the nitrogen heterocyclic ring aromatic compound. The method does not need transition metal, can be used for reducing production cost and environmental pollution, has an environment-friendly process, and can be used for preparing a series of novel compounds with illumination performance or pharmacological activity.
