Application In Synthesis of 2,3-Dichloroquinoxaline, New research progress on 2213-63-0 in 2021. As an important bridge between the micro and macro material world, chemistry is one of the main methods and means for humans to understand and transform the material world.2213-63-0, Name is 2,3-Dichloroquinoxaline, molecular formula is C8H4Cl2N2. In a article，once mentioned of 2213-63-0
The synthesis of four new dissymmetric cavitands is reported. These deep-walled receptors are constructed from a resorcin[4]arene scaffold bearing anti-disposed quinoxaline substituents, with either N-haloalkyl-diazaphthalimide (1), dinitrophenyl (2) or diaminophenyl (3) moieties as the other wall components. The structure and inclusion properties of 1 and 2 have been probed in solution by NMR spectroscopy and notably in the solid-state by X-ray crystallography. The diazaphthalimide-based compounds 1 crystallise as 1:1 host-guest complexes with chloroform, with the resorcin[4]arene scaffolds adopting pinched cone conformations. Conversely, the dinitrophenyl-variant 2 features a more open, symmetric structure in the solid-state and co-crystallises with two acetone molecules within the central cavity. Preliminary binding experiments in mesitylene-d12 at 303 K demonstrate 1 (Kapp = 5 × 102 M?1) and 2 (Kapp = 2 × 102 M?1) are effective hosts for cyclohexane guest molecules in the absence of competitive solvent inclusion.
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 2213-63-0, help many people in the next few years.Application In Synthesis of 2,3-Dichloroquinoxaline
