General description
2,3-Dimethyl-2-butene undergoes ozonolysis in dark to yield hydroxyl radical. Reaction of ozone with 2,3-dimethyl 2-butene was investigated using a flow-tube interfaced to UV photoelectron spectrometer. It forms adduct with thianthrene cation radical tetrafluoroborate at 0°C and -15°C.
Application
Used for the preparation of thexylborane.

Thianthrene cation radical tetrafluoroborate (Th*+ BF4-) has been found to add to 2,3-dimethyl-2-butene (DMB) at 0 degrees C and -15 degrees C. The adduct, 2,3-dimethyl-2,3-(5,10-thianthreniumdiyl)butane ditetrafluoroborate (12), was isolated at -15 degrees C, and its 1H NMR spectrum was recorded

In order to investigate the heterogeneous oxidation kinetics of the herbicide terbuthylazine (TERB), a stable and reproducible generation system of "dark" hydroxyl radical in the gas phase was developed and optimized using a PTR-MS. TERB was adsorbed on silica particles

Ultraweak chemiluminescence arising from lipoperoxidation has been attributed by several authors to the radiative deactivation of singlet oxygen and triplet carbonyl products. The latter emitters have been suggested to come from annihilation of RO. and ROO. radicals as well as
