Electrochemical Azolation of N-substituted Pyrroles: A New Case in SNH(An) Reactions
摘要:
Potentiostatic electrolysis (divided cell, anode compartment) of 1-methyl- and 1-phenylpyrroles in the presence of sodium 4-nitropyrazolate and sodium 3-nitropyrazolate in MeCN/MeOH gave the corresponding 2-(azol-1-yl)pyrroles in 20-43% current and substance yields.

biheterocyclic compounds were synthesized using cine substitution of 1,3-dinitro-1,2,4-triazole with different energetic moieties. All the compounds were fully characterized by multinuclear NMR and infrared spectra, and elemental analyses. The structures of 4, 7, 9, and 11 were confirmed by single-crystal X-ray structure analyses. Their physicochemical properties, such as density, thermalstability and sensitivity
