摘要

Abstract The 13 C [hexadeutero-dimethylsulfoxide (DMSO-d 6), hexamethyl-phosphoramide (HMPA)-d 18 and solid-state] and 15 N (solid-state) NMR spectra of six C- aminobenzimidazoles have been recorded. The tautomerism of 4 (7)-aminobenzimidazoles and 5 (6)-aminobenzimidazoles has been determined and compared with B3LYP/6-311++ G (d, p) calculations confirming the clear predominance of the 4-amino tautomer and the ...
