eAmidation: An Electrochemical Amidation of Aldehydes via the Oxidation of N‐Aryl Hydrazones

Advanced Synthesis &Catalysis, Volume 367, Issue 14, July 29, 2025.
The indirect electrochemical oxidation of N‐aryl hydrazones offers an efficient approach to access amides from aldehydes and amines. The AZADO‐mediated reaction enables the selective synthesis of a broad range of valuable amides using readily available aldehydes.

Synthesis of a novel series of chalcones and pyrazolines, possessing indole with 4-(2,2,2-trifluroethoxy) pyridine moiety

Orbital: The Electronic Journal of Chemistry, 2012
A new method for the construction of novel fluorine-containing indole ring system has been reported. These indoles were converted into a new series of fluorine-containing indolyl chalcones (1a-g) and pyrazolines (2a-g). All the newly synthesized
