Kinetics of the Diels–Alder Reaction of Thiofluorenone with 9,10-Dimethylanthracene

Abstract

Rate constants of the Diels–Alder reaction of thiofluorenone and 9,10-dimethylanthracene in toluene have been determined in the temperature range of 15 to 35°C, and the enthalpy and entropy of activation have been calculated. The structure of the resulting adduct was determined by NMR spectroscopy, mass spectrometry, and elemental analysis.
