In heterogeneous catalysis, the catalyst is in a different phase from the reactants. Formula: C8H4Cl2N2, 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
A Convenient and Single-Step Synthesis of Substituted 12H-Quinoxalino-<2,3-b><1,4>benzothiazines and -benzoxazines
Cyclocondensation of 2,3-dichloroquinoxaline (4) and the 2-aminothiophenols 1a-h or their zinc mercaptides 3a-h in the presence of alkaline dimethylformamide or in acidic medium afforded the corresponding 12H-quinoxalino<2,3-b><1,4>benzothiazines 7a-h in excellent yields.Similarly, the reaction of 4 with substituted 2-aminophenols 2 in the presence of base using dimethylformamide as solvent gave the 12H-quinoxalino<2,3-b><1,4>benzoxazines 7i-k.Acetyl derivatives of 7a-k were prepared.
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.Formula: C8H4Cl2N2
