The
differential scanning calorimetry (DSC) behavior of a number
of alkyne-rich compounds is described. The DSC trace for each compound
exhibits an exothermic event at a characteristic onset temperature.
For the tri- and tetraynes whose [4 + 2] HDDA reactivity in solution
has been determined, these onset temperatures show a strong correlation
with the cyclization activation energy. The studies reported here
exemplify how the data available through this operationally simple
analytical technique can give valuable insights into the thermal behavior
of small molecules.
