Rubazonic acids are a class of dyes that are long-known, but studies on their syntheses and uses are rare. We now describe an experimentally simple and highly practical one-pot procedure for their synthesis starting from easily accessible 1H-pyrazol-

The synthesis of previously unknown 3,3-diazidooxindoles as synthetically useful derivatives of isatins was accomplished through the direct oxidative diazidation of 2-oxindoles. The method yielded the diazido compounds from the starting oxindoles und

The degradation of geminal diazides is described. We show that diazido acetates are converted into tetrazoles through the treatment with bases. The reaction of dichloro ketones with azide anions provides acyl azides, through in situ formation of diaz
