Abstract
In a synthesis of tetrazoles from amides, diphenyl phosphorazidate or bis(p-nitrophenyl) phosphorazidate act as both the activator of amide-oxygen for elimination and azide source. Various amides were converted into 1,5-disubstituted and 5-substituted 1H-tetrazoles in good yields without the use of toxic or explosive reagents.
