Pyrolyses of 2-aminobenzazoles was written by Martineau, Andre;DeJongh, Don C.. And the article was included in Journal of Analytical and Applied Pyrolysis in 1983.Category: thiazole This article mentions the following:
The pyrolysis and mass spectral fragmentation of I (R = Ph, H; X = O, NH, S) follow similar paths and mechanisms. The replacement of H in I (R = H) by Ph allowed the observation of reaction intermediates, in both the pyrolysis and the mass spectra, which were too unstable for direct observation with I (R = H); the Ph group behaved as an internal trapping group. The M+ and (M – H)+ peaks are the most intense mass spectral peaks for I. In the experiment, the researchers used many compounds, for example, N-Phenylbenzo[d]thiazol-2-amine (cas: 1843-21-6Category: thiazole).
N-Phenylbenzo[d]thiazol-2-amine (cas: 1843-21-6) belongs to thiazole derivatives. The higher aromaticity of thiazole is due to delocalization of a lone pair of sulfur electrons across the ring, which is evidenced by chemical shifts of ring hydrogen at δ 7.27 and 8.77 ppm (C2 and C4), indicating diamagnetic ring current. Various laboratory methods exist for the organic synthesis of thiazoles. Prominent is the Hantzsch thiazole synthesis is a reaction between haloketones and thioamides.Category: thiazole
