Application of 1603-91-4, Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. 1603-91-4, Name is 4-Methylthiazol-2-amine, molecular formula is C4H6N2S. In a Article£¬once mentioned of 1603-91-4

2-Oxazolidinones are saturated heterocyclic compounds, which are highly attractive targets in modern drug design. Herein, we describe a new, single-step approach to 3,4-disubstituted 2-oxazolidinones by aza-Michael addition using CO2 as a carbonyl source and 1,1,3,3-tetramethylguanidine (TMG) as a catalyst. The modular reaction, which occurs between a gamma-brominated Michael acceptor, CO2 and an arylamine, aliphatic amine or phenylhydrazine, is performed under mild conditions. The regiospecific reaction displays good yields (av. 75 %) and excellent functional-group compatibility. In addition, late-stage functionalization of drug and drug-like molecules is demonstrated. The experimental results suggest a mechanism consisting of several elementary steps: TMG-assisted carboxylation of aniline; generation of an O-alkyl carbamate; and the final ring-forming step through an intramolecular aza-Michael addition.

Synthetic Route of 2289-75-0. Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 2289-75-0, Name is 4,5-Dimethylthiazol-2-amine

The corrosion behavior of iron in diluted aqueous sulfuric acid medium has been studied in the presence and absence of 6-ethoxybenzo[d]thiazol-2-amine (EBT), 5-bromothiazol-2-amine (BTA) and 4,5-dimethylthiazol-2-amine (DTA). Potentiodynamic measurements showed the shift of corrosion potential towards a more negative potential indicating that these compounds mostly act as cathodic inhibitors due to their adsorption on the iron surface. The adsorbed film of these molecules hinders the transport of metal ions from the metal to the solution and also retards hydrogen evolution reaction by acting as a physical barrier. The molecules were also studied by density functional theory (DFT), using the B3LYP functional in order to determine the relationship between molecular structure and the corrosion inhibition efficiencies.

This review paper aims to summarize significant researcher?s results dealing with potential copper corrosion inhibitors in the last few years. Due to its good properties such as good mechanical workability, thermal and electrical conductivity, copper is frequently used metallic material in different industrial fields and in daily life. However, it is known that exposure of copper in aggressive environments leads to its deterioration. Having this in mind, there is a need to protect copper from corrosion. The inhibition ability of different tested compounds such as azoles, amino acids, plant extracts, and pharmaceutical compounds is shown in this paper. To increase inhibition efficiency, different research groups examined the synergistic effect between different compounds. In addition, progress in the corrosion protection of materials has led to new trends in this field?development of superhydrophobic coatings as potential copper corrosion inhibitors. High surface roughness and low surface energy are essential for preparing superhydrophobic layers. To obtain surface of high roughness different methods such as chemical etching, chemical vapor deposition, and solution immersion method are used, because they are efficient, simple, and low-cost procedures.
