Application

Cyclopentene was used to investigate the [2+2] cycloaddition of diamond (001) surfaces with alkene.

General description

Cyclopentene is a cyclo-olefin. Neopentyl phosphine ligand catalyzed Heck coupling of cyclopentene has been reported. Mechanism of reaction of ground state oxygen atom with cyclopentene has been investigated. Homopolymerization of cyclopentene has been reported. Photocatalytic oxidation of cyclopentene over various titanium(IV) oxide catalyst has been reported.
