General description
2-Methyl-2-butene (β-Isoamylene, Amylene) is a trisubstituted olefin. It acts as guest and forms stable solid host-guest complexes with self-assembled benzophenone bis-urea macrocycles. The effect of active chlorine formulations on photodecomposition of 2-methyl-2-butene has been studied. Its reaction with ozone in gas-phase has been reported to afford carbonym derivatives.
Application
2-Methyl-2-butene may be employed as precursor for peroxyacetyl nitrate for the calibration purposes.
Other Notes
Brass hose adapter Z146811 or brass body mini gas regulator Z513539 is recommended.

This manuscript investigates how incorporation of benzophenone, a well-known triplet sensitizer, within a bis-urea macrocycle, which self-assembles into a columnar host, influences its photophysical properties and affects the reactivity of bound guest molecules. We further report the generation of a
