This paper represents an electrochemical transformation by demonstrating the dual role of an organic bromide salt, i.e., tetra-n-butylammonium bromide (TBAB), as a brominating agent and as an electrolyte for the regioselective bromination of several imida

We report herein an effective method for the halogenation of imidazo-fused heterocycles using readily available sodium salts (NaCl/NaBr/NaI) as halogen source and K2S2O8 (or) oxone as promoter. A variety of C-3 halogenated imidazo[1,2-a]pyridines and benzo[d]imidazo[2,1-b]thiazoles were obtained in good to excellent yields. The present method of halogenation has been also extended to 2-aminopyridines, 2-aminopyrimidine, indole, and isoquinoline with moderate to excellent yields.

, p. 855 - 860 (2007/10/02)
Fifteen imidazothiazoles containing a range of substituents at position 6 have been used in studies of electrophilic substitution at position 5.Acid-catalysed deuteriation was examined quantitively and, by making certain assumptions, values for the
