| General description: | 2,3-Dimethyl-2-butene undergoes ozonolysis in dark to yield hydroxyl radical. Reaction of ozone with 2,3-dimethyl 2-butene (DMB) has been investigated using a flow-tube interfaced to UV photoelectron spectrometer. DMB forms adduct with thianthrene cation radical tetrafluoroborate at 0°C and -15°C. |
