Synthesis of 1,3,5-trisubstituted-1,2,4-triazoles by microwave-assisted N-acylation of amide derivatives and the consecutive reaction with hydrazine hydrochlorides

Facile and efficient procedures for the N-acylation reaction of amide derivatives with various acid anhydrides and the cyclization reaction of N-acylated amide derivatives with various hydrazine hydrochlorides were described. The reactions were carried out under microwave irradiation to give products in good yields in a few minutes. The synthesis of 1,3,5-trisubstituted- 1,2,4-triazoles from benzamides can also be accomplished in a simple one-pot sequential reaction.

Synthesis of 1,2,4-Triazolium Salts: Reaction of 1-Azo-2-azonia-allene Salts with Nitriles

Alkyl ketone hydrazones 1 are oxidized with tert-butylhypochlorite to give geminal chloro azo compounds 2.These react with SbCl5 to give 1-aza-2-azonia-allene salts 3 as reactive intermediates which are intercepted with nitriles to yield 3H-1,2,4-triazoli

1,3-Dipolar Cycloadditions, 88. C-Methyl-N-phenylnitrilimine and the Regiochemistry of its Cycloadditions

The title compound, a representative of the little known C-alkylnitrilimines, is accessible by three routes: NaNO2 elimination from sodium (α-nitroethylidene)phenylhydrazine in boiling acetonitrile, photolysis of 5-methyl-2-phenyltetrazole, and the thermo

Synthese et reactivite de quelques α-amino azocomposes: mecanisme de la cyclisation thermique en triazoles-1,2,4

The reaction of O-mesitylenesulfonylhydroxylamine (MSH) with hydrazones leads to carbon amination with the formation of α-amino azo compounds.Thermolysis of these compounds affords 1,2,4-triazoles.The mechanism of this cyclization is discussed.
