Synthesis of Green/Blue Light Emitting Quinolines by Aza-D-A Reaction Using InCl3 Catalyst

An efficient InCl3-catalyzed sequential reaction of aromatic amines, aromatic aldehydes and functionalized alkynes leading to the formation of new quinoline derivatives exhibiting significant fluorescence activities is described. The photophysi

Observation of the complex spectra for the supramolecular system involving silver nanoparticles-biaryl Schiff bases containing the nitro group

A series of biaryl Schiff bases containing the nitro groups, 4-XArCH═NArNO2-4′ (XBANO2-4′) and 4-NO2ArCH═NArY-4′ (4-NO2BAY), were synthesized. Also, the fish sperm DNA (fsDNA) and silver nanoparticles (AgNPs) solutions were prepared. By mixing these compounds with fsDNA or AgNPs solution and determining the ultraviolet absorption spectra of the mixture solutions, an interesting phenomenon was found: a new absorption peak λmax,lim appeared in the (XBANO2-4′)-AgNPs solution, which was longer than the wavelength of λmax of XBANO2-4′ solution. The new absorption peak in the (XBANO2-4′)-AgNPs solution was the complex spectrum originating from the electron transfer between XBANO2-4′ and AgNPs. Whereas this phenomenon was not observed in the (4-NO2BAY)-AgNPs solutions, a quantitative correlation analysis was carried out with the measured spectral data, and the results show that the wave number νmax,lim of the λmax,lim is mainly affected by the excited-state substituent constant (Formula presented.) rather than the ground Hammett constant σ of the X group. The redshift magnitude Δνmax,WSL, namely, Δνmax,WSL = (1/λmax) ? (1/λmax,lim), of the wavelength λmax,lim is related to the highest occupied molecular orbital and lowest unoccupied molecular orbital of XBANO2-4′. The discovery of this new phenomenon is helpful to understanding the interaction between AgNPs-organic compound supramolecular systems.

Dehydrogenation and α-functionalization of secondary amines by visible-light-mediated catalysis

A visible-light-mediated process for dehydrogenation of amines has been described. The given protocol showed a broad substrate scope, mild reaction conditions and excellent results without the requirement of tedious purification. This process can be applied in one-pot functionalization of secondary amines with various nucleophiles through the cooperation of visible-light and Lewis acid catalysis, leading to the structurally varied essential components of biologically active molecules. In addition, Stern-Volmer studies and quenching experiments revealed the role of a catalyst and led to the proposed mechanism of this transformation.

Dual Heterogeneous Catalyst Pd-Au@Mn(II)-MOF for One-Pot Tandem Synthesis of Imines from Alcohols and Amines

A new Mn(II) metal-organic framework (MOF) 1 was synthesized by the combination of 4,4,4-trifluoro-1-(4-(pyridin-4-yl)phenyl)butane-1,3-dione (L) and Mn(OAc)2 in solution. 1 features a threefold-interpenetrating NbO net containing honeycomb-like channels, in which the opposite Mn(II)···Mn(II) distance is 23.5075(10) ?. Furthermore, 1 can be an ideal platform to support Pd-Au bimetallic alloy nanoparticles to generate a composite catalytic system of Pd-Au@Mn(II)-MOF (2). 2 can be a highly active bifunctional heterogeneous catalyst for the one-pot tandem synthesis of imines from benzyl alcohols and anilines and from benzyl alcohols and benzylamines.

Silver-catalyzed one-step synthesis of multiply substituted quinolines

A silver-catalyzed formation of C-C bond for the construction of a series of polysubstituted quinolines from arylamines, aldehydes, and ketones or arylamines and 1,3-diketones has been developed. The transformation is effective for a broad range of substrates, thus enabling the expansion of constituent architectures on the heterocyclic framework. This use of a single catalytic system to mediate chemical transformations in a synthetic operation is important for the development of new atom-economic strategies and this strategy is efficient in building complex structures from simple starting materials in an environmentally benign fashion.

Mechanochemical milling promoted solvent-free imino Diels-Alder reaction catalyzed by FeCl3: Diastereoselective synthesis of cis-2,4-diphenyl-1,2,3,4-tetrahydroquinolines

Under mechanochemical ball-milling at room temperature, FeCl3 promoted Diels-Alder cycloaddition of styrene with in situ generated N-aryl aldimines in the absence of any solvent afforded exclusively cis-2,4-diphenyltetrahydroquinolines in good to excellent yields within 90 minutes. The isolation work up just involves washing the resulting reaction mixture with water and recrystallization from EtOH-H2O. The advantages of high diastereoselectivity, short reaction time, free use of organic solvent, low cost, employment of cheap, easily available and nontoxic catalyst, and simple work-up procedure make this protocol a very efficient and green alternative to traditional methods for constructing these kinds of heterocyclic skeletons.
