methyl 3-phenylpropyl sulfone in the gas phase results in formation of allylbenzene. Activation parameters of ΔH⧧ = 53.5 ± 1.0 kcal/mol and ΔS⧧ = −0.7 ± 1.4 cal/(mol·K) were obtained over the range of 490−550 °C. Similar measurements with a deuterated analogue show a substantial isotope effect, and a lower activation enthalpy is observed for the formation of styrene from methyl 2-phenylethyl sulfone
