The cyanoethylation of derivatives of 5-chloro-1,2,3-triazolecarboxylic acids was studied, and it was shown by mass spectrometry and 1H NMR spectroscopy that the only products of this reaction are 2-N-cyanoethyl derivatives.

The 2-carbonyl derivatives of diazoacetonitrile react reversibly with hydrogen halides to form 1:2 adducts, in which one molecule of the hydrogen halide is coordinated with the nitrogen atom of the cyano group while the other is coordinated with the carbonyl group.The cyclization of the adducts in the solid phase and also the cyclization of the diazoacetonitrile derivatives in ethanol by the action of hydrogen halides to the 5-halogeno-1,2,3-triazoles takes place as a reaction of first order with respect to the diazo compound.The liquid-phase reaction is of second order in the hydrogen halides.

Reaction of nitrous acid with 4-substituted and 4,6-disubstituted 5-aminopyrimidines Ia-In produces 4-substituted and 4,5-disubstituted 1,2,3-triazoles IIa-IIv, resp.Under similar conditions, 2,5-diaminopyrimidines XIIa-XIId give N(7)-oxides of 2-amino-4-aralkylthiopyrimido-1,2,3-triazines XIIIa-XIIId, and 5-amino-4-chloropyrimidines In and X give 2-diazocyanoacetamides XIa and XIb, resp.Also described are syntheses of 5-formylaminopyrimidines XVa-XVg from glycine ethyl ester via sodium salt XVI.
HETEROCYCLIC COMPOUNDS CONTAINING DIAZO AND CYANO GROUPS. 1. DIAZOACETONITRILE DERIVATIVES IN THE SYNTHESIS OF 5-HALO-1H-1,2,3-TRIAZOLES

, p. 1038 - 1043 (2007/10/02)
Carbonyl-substituted derivatives of diazoacetonitrile have been obtained by the diazotation of amines and by diazo-group transfer which, under the action of hydrogen halide, have been converted into 4-carbonyl-substitued 5-halo-1H-1,2,3-triazoles.The stru

1-Nucleosides of 5-substituted 4-chloro-1,2,3-triazoles were produced by glycosylation of the corresponding triazoles by the method of fusion with tetra-O-acyl-D-ribofuranose in the presence of bis-p-nitrophenyl phosphate.The structure of the compounds ob
