Abstract: Differential Scanning Calorimetry (DSC) has been shown to provide useful information in organic synthesis in the stage of planning thermolytical reactions [1]. This information can be obtained before the reaction itself is performed and include the temperature range of the planned reaction, hints on subsequent rearrangement and decomposition reactions, choice of suitable solvents and safety precautions in exothermic processes.

Another point of interest is that also reactions with two reaction partners and the influence of solvents on the reaction temperature can be studied.

In this contribution three examples of DSC applications in organic synthesis will be presented, which deal mainly with thermolytic reactions of ortho-substituted organic azides and subsequent reactions

  • Thermolytic cyclization of ortho-azidohetarene carboxylates to isoxazols and subsequent rearrangement by migration of the alkoxy group from the isoxazolo to the hetarene ring system
  • Thermolytic ring closure of ortho-nitroazides and study of the influence of solvents
  • Reaction of furoxanes with triphenylphosphane to oxadiazoles by deoxygenation.
