Tetrazolium N-aminides

Tetrazolium N-aminides. Moderhack, Dietrich; Noreiks, Matthias (Institute of Pharmaceutical Chemistry, Technical University, Braunschweig D-38106, Germany). Heterocycles, 63(11), 2605-2614 (English) 2004 Japan Institute of Heterocyclic Chemistry. CODEN: HTCYAM. ISSN: 0385-5414. DOCUMENT TYPE: Journal CA Section: 28 (Heterocyclic Compounds (More Than One Hetero Atom)) Section cross-reference(s): 22 Tetrazolium N-aminides, e.g., I, have been prepd. by acylation of the tetrazolium salts. These tetrazolium N-aminides were fully characterized. 820961-06-6 and 16681-77-9 are also in the experiment. The preferred geometries of some of the tetrazolium N-amidines have been detd. by a Hartree-Fock and D. Functional Theory calcn. [HF/6-31G(d), B3LYP/6-31G(d)]. .

Tetrazoles

Tetrazoles. XVII. Mass spectrometry of 1-methyl- and 2-methyl-5-aryltetrazoles. Shurukhin, Yu. V.; Klyuev, N. A.; Ostrovskii, V. 16681-77-9 is the cas registry number. This chemical is also mentioned in this article. A.; Koldobskii, G. I.; Erusalimskii, G. B. (Leningr. Tekhnol. Inst., Leningrad, USSR). Zh. Org. Khim., 20(11), 2458-64 (Russian) 1984. CODEN: ZORKAE. ISSN: 0514-7492. DOCUMENT TYPE: Journal CA Section: 22 (Physical Organic Chemistry) The mass spectra of the title compds. I (R = H, Me, Br; R1 = Me, CD3) and II (same R, R1) were analyzed. Mol.-ion peaks of anomalously high intensity as well as peaks at [M-N3]+, [M-CH2N2]+, and [MeN2]+ appeared in the spectra of I but not II. These findings were consistent with tetrazole basicities and MO calcns. and were related to tautomerism in I. .
