In heterogeneous catalysis, the catalyst is in a different phase from the reactants. Product Details of 2213-63-0, At least one of the reactants interacts with the solid surface in a physical process called adsorption in such a way. 2213-63-0, name is 2,3-Dichloroquinoxaline. In an article£¬Which mentioned a new discovery about 2213-63-0
Alkynyl- and Dialkynyl-quinoxalines. Synthesis of Condensed Quinoxalines
Condensation of 2-chloro- and 2,3-dichloroquinoxalines with alk-1-ynes in the presence of bis(triphenylphosphine)palladium(II) dichloride and copper(I) iodide gives mono- and di-alkynylquinoxalines.Addition of amines to these products gives stable enamines; hydration gives 2′-oxoalkyl compounds which exist predominantly in the intramolecularly hydrogen-bonded enol form.Condensation of the alkynylquinoxalines with diethyl sodiomalonate, and related compounds, yields pyrido<1,2-a>quinoxalin-4-one derivatives. 2-Alkynyl-3-chloroquinoxalines are intermediates for convenient syntheses of pyrrolo<2,3-b>quinoxalines.
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.Product Details of 2213-63-0
