Рубрики: ХИМИЧЕСКИЕ НАУКИ Кл.слова (ненормированные): SYNTHESIS -- 2-AZIDO-5-NITROPYRIMIDINE -- AZIDO-TETRAZOLE TAUTOMERISM Аннотация: We describe the synthesis of 2-azido-5-nitropyrimidine and its azido-tetrazole tautomerism in various solvents and in the crystalline state. It was established that on interacting with N-nucleophiles the attack occurred at the C-2 carbon atom. The O- and S-nucleophiles attacked C-4 position of pyrimidine ring, resulting in tetrazole ring closure \\\\expert2\\NBO\\Chemistry of Heterocyclic Compounds\\2013, v.49, N 5, p. 765-775.pdf |
