Abstract

The decomposition of acetylenedicarboxylic acid in acetophenone was studied in the temperature range of 100–130°C. The rate constants and activation parameters for the consecutive pair of first‐order steps (each yielding carbon dioxide) were calculated. Hydrogen kinetic isotope effects were also studied. Comparisons were made with the decompositions of oxalic acid and malonic acid. An intramolecular HC transfer is believed to be the main part of the reaction coordinate in addition to the CC bond breaking.
