The invention discloses a method of electrochemically synthesizing a 1, 2, 4-triazole compound. The method includes: dissolving a compound (I) and quaternary ammonium salt into acetonitrile, stirringat room temperature of 50 DEG C to obtain reaction liqui

Intramolecular electrochemical dehydrogenative N-N bond formation for the synthesis of 1,2,4-triazolo[1,5-a] pyridines

A metal- and oxidant-free intramolecular dehydrogenative N-N bond formation has been developed under mild and scalable electrolytic conditions. Various valuable 1,2,4-triazolo[1,5-a]pyridines were synthesized efficiently from the readily available N-(2-pyridyl)amidines. The reactions were conducted in a simple undivided cell under constant current conditions with nBu4NBr as both the redox mediator and the electrolyte. This protocol was applied to the efficient synthesis of key intermediates for anti-diabetic compounds.

An effective and expeditious approach for the construction of biologically important 5-guanidino-1,2,4-thiadiazole and 1,2,4-triazolo[1,5- a ]pyridine derivatives has been developed. This new protocol involves the phenyliodine(III) diacetate [PhI(OAc) su

Heterogeneous Copper(I)-Catalyzed Cascade Addition-Oxidative Cyclization of Nitriles with 2-Aminopyridines or Amidines: Efficient and Practical Synthesis of 1,2,4-Triazoles

The heterogeneous cascade addition-oxidative cyclization of nitriles with 2-aminopyridines or amidines was achieved in 1,2-dichlorobenzene or DMSO at 120-130 °C by using a 1,10-phenanthroline-functionalized MCM-41-supported copper(I) complex [Phen-MCM-41-

Facile synthesis of 1,2,4-triazoles via a copper-catalyzed tandem addition-oxidative cyclization

A simple one-step synthesis of 1,2,4-triazole derivatives is provided by a copper-catalyzed oxidative coupling reaction under an atmosphere of air. The process should consist of sequential N-C and N-N bond-forming copper-catalyzed oxidative coupling reactions. Starting materials and the copper catalyst are readily available and inexpensive. A wide range of functional groups are tolerated to achieve chemical diversity.
