ANRORC PROCESS IN 1-ALKYLAZOLO[5,1-c][1,2,4]TRIAZIN-4(1H)-ONES

Abstract
Nucleophilic substitution of nitro group in 1-alkylazolo[5,1-c][1,2,4]triazin-4(1H)-ones proceeds according to the ANRORC mechanism, involving the opening of azine ring, nucleophilic substitution, and cyclization. The structures of all intermediates were confirmed by spectral data.
Keywords
