23031-78-9, Name is Benzo[d]isothiazol-3-amine, molecular formula is C7H6N2S, belongs to thiazole compound, is a common compound. In a patnet, once mentioned the new application about 23031-78-9, Formula: C7H6N2S
3-Amino-4-methyl-6-phenyl-1H-pyrazolo<3,4-d>pyrimidine (3a) and 3-amino-4-methyl-6-phenylisothiazolo<5,4-d>pyrimidine (9a) have been prepared.The former reacts with bromoacetone or 3-bromopentane-2,4-dione, to give tricyclic systems (1a) or (13) containing an extra pyrazole or pyrimidine ring, respectively; in each case the newly formed ring contains a bridgehead nitrogen atom, derived from N-2 of the starting material.With the same reagents, the latter undergoes an interesting ring-opening reaction, for which possible mechanisms are proposed.In contrast, 3-amino-1,2-benzisothiazole does not undergo ring fission under similar conditions, but gives rise to tricyclic compounds containing a bridgehead nitrogen atom.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.Formula: C7H6N2S. In my other articles, you can also check out more blogs about 23031-78-9
