Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 348-40-3, Name is 6-Fluorobenzo[d]thiazol-2-amine, Quality Control of: 6-Fluorobenzo[d]thiazol-2-amine.
Synthesis and structure of some 3,4-annelated coumarin systems
Refluxing of 4-chlorocoumarin-3-carbonitrile, heteroarylamines (3-aminopyrazole, 3-aminopyrazole-4-carbonitrile, 3-amino-1,2,4-triazole-5-thiol, 2-amino-6-fluorobenzothiazole, 2-amino-pyridin-3-ol, 1-aminoisoquinoline) and the catalytic amount of trimethylamine in acetonitrile gave the corresponding 3,4-annelated coumarins 1-6 in high yields. The spectral analysis showed that 7-amino-5-oxa-7a,8,11-triazacyclopenta[b]phenantren-6-one (1) existed as enamine, 2 as a mixture of enamine 7-amino-6-oxo-5-oxa-7a,8,11-triazacyclopenta[b]phenantren-10-carbonitrile (2a) and imine 7-imino-6-oxo-7H,8H-5-oxa-7a,8,11-triazacyclopenta[b]phenantren-10- carbonitrile (2b), whereas 10-fluoro-7-imino-7H-5-oxo-12-thia-7a,13-diazaindeno[1,2-b]phenantren-6-one (4), 11-hydroxy-7-imino-7H-7a,12-diazabenzo[a]anthracen-6-one (5) and 7-imino-7H-5-oxa-7a,14-diazadibenzo[a,h]anthracen-6-on (6) took imino forms.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.Quality Control of: 6-Fluorobenzo[d]thiazol-2-amine. In my other articles, you can also check out more blogs about 348-40-3
