General description

2-Methyl-2-butene is a trisubstituted olefin. It acts as guest and forms stable solid host-guest complexes with self-assembled benzophenone bis-urea macrocycles. The impact of active chlorine on photo-oxidation of 2-methyl-2-butene was studied. Photosensitized oxidation of 2-methyl-2-butene adsorbed on internal framework of Na-ZSM-5 zeolite was studied. Gas-phase reaction of 2-methyl-2-butene with ozone has been investigated. Kinetics of liquid-phase alkylation of 3-methylthiophene with 2-methyl-2-butene on supported phosphoric acid has been reported.

2-methyl-2-butene undergoes ultraviolet irradiation, leading to the formation of trimethylene oxides.

Application

2-Methyl-2-butene may be employed as precursor for peroxyacetyl nitrate for the calibration purposes.

Rhizopus arrhizus is a common pathogenic Mucoralean mold that exists as a saprophyte, and is disseminated through sporangiospores, which germinate to form mycelia under suitable environmental or infection settings. Such morphological transitions are often mediated by self-produced effector molecules in

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
