Electrochemical reduction of 1-Aryl-4-nitroazoles

Tallec A., Hazard R., Suwiński J., Wagner P.

Polish Journal of Chemistry

2000

Vol. 74, nr 8

1177-1183

Electrochemical reduction of the nitro group in 1-aryl-4-nitroazoles occurs in slightly acidic medium as a typical four-electron process leading to hydroxylamine group formation. The forming 1-aryl-4-hydroxylaminoazoles undergo further reactions. Some products of this transformations, following the electrochemical reduction, were isolated and their structure were fully characterized by standard methods.

Reductive acylation of 4-nitroazoles. Synthesis of N-(4-azolyl)acetamides, N-(4-azolyl)succinimides and N-(4-azolyl)phthalimides

Suwiński J., Wagner P.

Polish Journal of Applied Chemistry

2000

Vol. 44, nr 1

31-35

N-Azolylamides have been obtained by the reductive acylation of nitroazoles with acetic, succinic or phthalic anhydrides. N-Azolylsuccinamic and Af-azolylphthalamic acids forming from nitroazoles and the cyclic anhydrides have been cyclocondensed by the treatment with acetic anhydride - sodium acetate mixture to give respective N-azolylimides.
