Abstract

The carbon-13 NMR spectra of 57 benzothiazoles including 6-substituted 2- aminobenzothiazoles (11, 6-substituted 2-methylbenzothiazoles (Z), 6-substituted benzothiazoles (3), 5-substituted 2-methylbenzothiazoles (4) and 2-substituted benzothiazoles (5) were determined in MepSO-ds. The chemical shift assignments were made based upon the ones previously reported for benzothiazole, 2-aminobenzothiazole, ...
