The synthesis of quinolines: via denitrogenative palladium-catalyzed cascade reaction of o -aminocinnamonitriles with arylhydrazines

The first example of the palladium-catalyzed cascade reaction of o-aminocinnamonitriles with arylhydrazines has been achieved, providing an efficient synthetic pathway to access quinolines with moderate to good yields. Preliminary mechanistic experiments

Rh(iii)-catalyzed alkynylation: Synthesis of functionalized quinolines from aminohydrazones

Rhodium-catalyzed, chemo- and regioselective synthesis of functionalized quinolines using 2-aminohydrazones and terminal alkynes has been described. The reaction is oxidant/base-free and tolerates a wide variety of functional groups and has been successfu

Direct arylation for the synthesis of 2-arylquinolines from N-methoxyquinoline-1-ium tetrafluoroborate salts and arylboronic acids

A rapid and direct arylation reaction of N-methoxyquinoline-1-ium tetrafluoroborate derivatives and arylboronic acids with high regioselectivety at room temperature was discovered. The reaction shows exceptional functional group tolerance and broad substrate scope regarding both the quinoline derivatives and the arylboronic acids.

KMnO4-mediated direct selective radical cross-coupling: An effective strategy for C2 arylation of quinoline N-oxide with arylboronic acids

Direct C[sbnd]H functionalization of quinoline N-oxides with arylboronic acids is achieved using KMnO4 as the sole and efficient oxidative system. This method provides an efficient protocol to construct regioselectively 2-arylquinoline N-oxides

Simple and Clean Photo-induced Methylation of Heteroarenes with MeOH

Heteroarene methylation utilizing a cheap and safe methylation source without involving transition metals represents an important yet challenging objective. Here, a simple and clean catalyst-free protocol for the methylation of various heteroarenes (including six- and five-membered types) is described under light irradiation. This protocol employs cheap, readily available, and abundant MeOH as both the solvent and the methylation source. It was found that adding dichloromethane (DCM) as a co-solvent could significantly increase the yield of the methylation products. Heteroarenes bearing various functional groups could be methylated and tri-deuteromethylated successfully. Deuterium labeling studies suggested that the newly generated methyl group in the products consisted of two hydrogens from the methyl group and one hydrogen from the OH group in MeOH.

Iron-Catalyzed Cyclization of Nitrones with Geminal-Substituted Vinyl Acetates: A Direct [4 + 2] Assembly Strategy Leading to 2,4-Disubstituted Quinolines

An iron-catalyzed intermolecular [4 + 2] cyclization of arylnitrones with geminal-substituted vinyl acetates was developed for the synthesis of 2,4-disubstituted quinolines in moderate to good yields with good functional group compatibilities. Preliminary mechanistic studies suggest a plausible iron-catalyzed C-H activation process under external-oxidant-free conditions.

Facile Synthesis of Highly Efficient Lepidine-Based Phosphorescent Iridium(III) Complexes for Yellow and White Organic Light-Emitting Diodes

Highly efficient lepidine-based phosphorescent iridium(III) complexes with pentane-2,4-dione or triazolpyridine as ancillary ligands have been designed and prepared by a newly developed facile synthetic route. Fluorine atoms and trifluoromethyl groups have been introduced into the different positions of ligand, and their influence on the photophysical properties of complexes has been investigated in detail. All the triazolpyridine-based complexes display the blueshifted dual-peak emission compared to the pentane-2,4-dione-based ones with a broad single-peak emission. The complexes show emission with broad full width at half maximum (FWHM) over 100 nm, and the emissions are ranges from greenish-yellow to orange region with the absolute quantum efficiency (ΦPL) of 0.21-0.92 in solution, i.e., ΦPL = 0.92 (18), which is the highest value among the reported neutral yellow iridium(III) complexes. Furthermore, high-performance yellow and complementary-color-based white organic light-emitting diodes (OLEDs) have been fabricated. The FWHMs of the yellow, greenish-yellow OLEDs are in the range of 94-102 nm, which are among the highest values of the reported yellow or greenish-yellow-emitting devices without excimer emission. The maximum external quantum efficiency of monochrome OLEDs can reach 24.1%, which is also the highest value among the reported yellow or greenish-yellow devices. The color rendering indexes of blue and complementary yellow-based white OLED is as high as 78.
