salts and their corresponding triazenes have
been prepared in order to directly compare their relative thermal
stabilities (via initial decomposition temperature) from differential
scanning calorimetry (DSC) data. A structure–stability relationship
has been explored to investigate trends in stability, depending on
the aromatic substituent and the structure of the secondary amine
component of the diazonium salts and triazenes. All of the triazenes
investigated show significantly greater stability (many are stable
above 200 °C) compared with the corresponding diazonium salts,
which show varying stabilities.
