Usage

General Description

2,5,7-Trimethylquinoline, also known as TMQ, is an organic compound belonging to the class of quinolines. It is a light yellow liquid with a strong, aromatic odor, and is insoluble in water but soluble in organic solvents. TMQ is commonly used as a fragrance ingredient in consumer products such as perfumes, soaps, and detergents. It is also used as an intermediate in the synthesis of other chemicals and as a stabilizer in the manufacturing of rubber compounds. TMQ has been identified as a potential environmental contaminant, and its toxicity and impact on human health and the environment are subject to ongoing research and evaluation.

Nano Pt-TiO2 for an efficient one-pot photocatalytic synthesis of quinaldines from anilines and ethanol

Nanosized platinum particles loaded on the TiO2 nanoparticles were prepared to assess its photocatalytic activity in simple one-pot synthesis of quinaldines from anilines in ethanol using UV light. The catalyst was characterized by X-ray diffra

Novel redox photocatalyst Pt-TiO2 for the synthesis of 2-Methylquinolines from nitroarenes

An eco-friendly and efficient procedure for synthesis of 2-methylquinoline derivatives from nitroarenes has been developed by a simple one-pot reaction on the surface of platinum-loaded TiO2 with neat ethanol under UV irradiation without any harsh reagent according to green chemistry. TiO 2 catalysts with various amounts of Pt loadings were prepared by photodeposition using chloroplatinic acid solution and characterized by XRD, BET, AFM, HR-TEM, XPS, and DRS. XRD patterns showed that the crystal structure of Pt-TiO2 still remained as anatase phase. The UV-vis spectra indicated that Pt promoted the absorption of visible light. The XPS measurements reveal that platinum particles are present mainly in metallic form. AFM and HR-TEM analysis revealed the presence of nonspherical shaped platinum nanoparticles of the diameter 312 nm. Pt-TiO2 on irradiation induces a combined redox reaction with nitroarene and alcohol and this is followed by condensationcyclization of aniline and oxidation products to give 2-methylquinolines

Preparation of Tetradentate Copper Chelators as Potential Anti-Alzheimer Agents

The uncontrolled redox activity of metal ions, especially copper, in the brains of patients with Alzheimer's disease (AD) should be considered the origin of intense oxidative damage to neurons in the AD brain. To obtain low-molecular-weight copper chelators that act as tetradentate ligands, we designed new compounds based on an 8-aminoquinoline motif with a lateral chain attached at the 2-position of the aromatic ring. Some of these new ligands, termed TDMQ for TetraDentate MonoQuinolines, are specific for copper chelation. Full characterization of these ligands is reported, as well as their affinities for CuII, and their capacities to inhibit oxidative stress induced by copper–amyloids activated by a reductant. Such metal ligands can be considered as potential anti-AD agents, as they should be able to regulate the homeostasis of copper in brain tissue.

Preparation method of quinoline derivative

The invention provides a preparation method of a quinoline derivative. The method includes the steps of: in the presence of an oxidizing agent, adding a catalyst, then adding aniline or aromatic amine with different substituents, at the same time adding alcohol for reaction so as to prepare the quinoline derivative by one step. Specifically, the catalyst comprises a metal catalyst, an assistant catalyst I and an assistant catalyst II; the metal catalyst is a transition metal catalyst; the assistant catalyst I is an alkaline nitrogen-containing ligand; and the assistant catalyst II is an acidic compound. The quinoline derivative prepared by the method provided by the invention has stable performance and high purity. And the preparation method of the quinoline derivative can prepare quinoline, 2-methylquinoline, 8-hydroxyquinoline quinoline and other derivatives by one-step reaction, and the preparation method is simple and practicable. The preparation process does not produce new "three wastes", is environment-friendly, and provides a green and environment-friendly synthesis method. The preparation method has the characteristics of few raw material variety, little reaction equipment, few preparation step and low cost, and is more suitable for industrial production.
