Abstract
| - A versatile and highly efficient protocol for the synthesis of1,5-disubstituted tetrazoles has been developed by metaltriflate catalyzed one-pot reaction of alkenes, NBS, nitriles,and TMSN3. Among the metal triflates, Zn(OTf)2 was foundto be the best catalyst. Use of different combinations ofalkenes and nitriles generate a variety of 1,5-disubstitutedtetrazoles containing an additional α-bromo functionality ofthe N1-alkyl substituent.
