1,3,5-Trioxane-2,4,6-trione
(cyclic trimer of CO<sub>2</sub>) is
the product of a four-step synthesis: chlorination of isobutyraldehyde;
cyclotrimerization of 2-chloro-2-methylpropanal; dehydochlorination
of 2,4,6-tris(2-chloropropan)-2-yl-1,3,5-trioxane; ozonolysis at −80
°C of 2,4,6-tri(propan-2-ylidene)-1,3,5-trioxane. This trioxane-trione
is detected in solution at temperatures between −80 to −40
°C, and its conversion to CO<sub>2</sub> is monitored by <sup>13</sup>C NMR and FTIR. The CO<sub>2</sub> trimer has a half-life
of approximately 40 min at −40 °C.
