COA of Formula: C8H4Cl2N2, New Advances in Chemical Research in 2021. The transformation of simple hydrocarbons into more complex and valuable products via catalytic C–H bond functionalisation has revolutionised modern synthetic chemistry. 2213-63-0, Name is 2,3-Dichloroquinoxaline, molecular formula is C8H4Cl2N2. In a article，once mentioned of 2213-63-0
Resorcin[4]arene-based molecular baskets, with four free or methylene-bridged HO groups, and water-soluble container molecules bearing poly(ethylene glycol) chains of different lengths on the lower rim and cap have been synthesized. These cavitands, topped with p-xylylene bridges, feature well-defined cavities capable of encapsulating heteroalicyclic guests. Association constants (Ka) were determined by 1H NMR spectroscopy for the organic-soluble molecular baskets in CDCl3 and for the water-soluble container molecules in D2O/CD3CN (2:1). Opposite guest selectivities were observed in the two environments. Upon complexation, the water-soluble hosts show changes in their 1H NMR spectra. In the absence of guests, the p-xylylene bridge rotates rapidly on the 1H NMR timescale, revealing a time-averaged achiral C2v structure, whereas this rotation is hindered by guest inclusion, resulting in spectra showing a racemic C2-symmetric host, indicative of planar chirality.
