Synthetic Route of 6640-47-7, We’ll be discussing some of the latest developments in chemical about CAS: 6640-47-7, name is Quinoxaline-2,3-diamine. In an article，Which mentioned a new discovery about 6640-47-7

A new approach to selected 1,2,4-benzotriazines has been developed. 3,3,6,6-Tetrachloro-1,2-cyclohexanedione reacted with 2-pyridylamidrazones to give unexpected isolable bishemiaminal intermediates instead of the corresponding ketodiazenes. Subsequent dehydration gave 5,5,8,8-tetrachloro-3- (2-pyridyl)-5,6,7,8-tetrahydrobenzo[e][1,2,4]triazines, which were converted into previously unknown 5,8-dichloro-3-(2-pyridyl)benzo[e][1,2,4]triazines by dehydrochlorination under basic conditions. Severe limitations of reactions between o-benzoquinones with amidrazones have been circumvented in this manner. This preparative process has also been adapted to a one-pot protocol.

A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 6640-47-7

Non-symmetrical 2,3-disubstituted quinoxalines are not easily obtained in good yields because of the lack of regioselectivity of the Hinsberg condensation, or the large number of steps required for achieving their preparation. Two efficient methods leading to non-symmetrical 2,3-disubstituted quinoxalines, carried out in smooth conditions, have been developed in our laboratory. These methods enable the synthesis of pharmacologically active quinoxaline derivatives.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.
