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.
Synthesis of substituted five- and six-membered nitrogen heterocycles from 1-chloro-2-azapropenylium and 1-chloro-2,4-diazabutenylium salts
Okide, George B.
, p. 422 - 426 (2007/10/02)
Substituted pyrimidine, 1,2,4-triazole and 1,2,4-oxadiazole have been synthesized from various tertiary amides.The secondary amides give 1,3,5-triazinium perchlorates via, in most cases isolable acyclic triazahexadienylium intermediates.
