  Copper-Mediated Sequential C–N and N–N Bond Formation: Facile Synthesis of Symmetrical 1,2,4-Triazoles

  摘要：

  Via a one-pot process, catalyzed by Cu(OAc)(2), a series of 3,5-disubstituted 4H-1,2,4-triazoles was conveniently and efficiently synthesized by using low-toxicity, stable, readily available, inexpensive amidine hydrochloride.

  A number of symmetrical 3,5-disubstituted-4H-1,2,4-triazoles have been synthesized in good yields by deamination of the corresponding 4-amino-1,2,4-triazoles via reductive diazotation of these amino compounds in the presence of hypophosphorous acid. Analytical, spectral data and theoretical calculations confirmed the structures of the new triazole derivatives.

  Two methods for the synthesis of 3,5-diaryl-1,2,4-triazoles, both domino reactions, are reported. The first procedure, the Cu(OTf)(2)-catalyzed reaction between two amidines using NaHCO3 as a base, 1,10-phenanthroline as an additive and K-3[Fe(CN)(6)]/atmospheric oxygen as the oxidant, delivers 3,5-diaryl-1,2,4-triazoles with yields up to 68%. The second procedure for the synthesis of 3,5-diaryl-1,2,4-triazoles with yields up to 64% rests on the Cu(OTf)(2)-catalyzed reaction between two imidates and ammonium carbonate. This method features the formation of three bonds in a single synthetic step. (C) 2014 Elsevier Ltd. All rights reserved.
