  Reaction of 5-Substituted tetrazoles with trifluoroacetic anhydride

  摘要：

  5-Substituted tetrazoles readily react with trifluoroacetic anhydride at 20-25 degrees C to give the corresponding 2-substituted 5-trifluoromethyl-1,3,4-oxadiazoles, in contrast to published data according to which the title compounds are converted into 1,3,4-oxadiazole derivatives on heating with carboxylic acid anhydrides or chlorides at 100-120 degrees C. The reaction is governed not only by the rate of acylation of the tetrazole ring and temperature conditions but also by the stability of intermediate N-acyltetrazoles.
