- Abstract
2-Aminobenzothiazolinium nitrate ( 1) was characterized by elemental analysis, melting point, IR, 1H NMR, and X-ray crystallography. The driving force for the 2-aminobenzothiazole tautomerism in methanol solution was studied using theoretical calculations. It is suggested that the 2-aminobenzothiazolinium cation is an intermediate product between the amino form ( 2) and imino form ( 3) of 2-aminobenzothiazole. The tautomerization reaction can proceed in two steps through protonation and deprotonation between the two forms 2 and 3.
