Kinetics of the thermal gas-phase decomposition of 6-oxabicyclo[3,1,0]hexane

Abstract

The kinetics of the gas-phase decomposition of 6-oxabicyclo[3,1,0]hexane have been studied over the temperature range 670–742 K at pressures between 1 and 28 Torr. Isomerization to cyclopentanone and cyclopent-2-en-1-ol accounts for ∼97 % of the primary reaction products and occurs by first-order, homogeneous, non-radical processes. k_{cyclopentanone}/s^–1= 10^14.16∓0.11 exp(– 240 400∓1500/8.314T), k_{cyclopent-2-en-1-ol}/s^–1= 10^13.56∓0.16 exp(– 242 200∓2200/8.314T)
