Exempel på hur man kan använda CYCLOBUTENE i en mening

• Monocyclic cycloalkenes are cyclopropene, cyclobutene, cyclopentene, cyclohexene, cycloheptene, cyclooctene, and so on.
• Some cycloalkenes, such as cyclobutene and cyclopentene, can be used as monomers to produce polymer chains.
• Enone–alkene cycloadditions - photochemical reaction of an enone with an alkene to give a cyclobutene ring unit.
• For the photoinduced ring opening of cyclobutene, is it shown that the disrotatory motion predicted by the Woodward–Hoffmann rules is established within the first 50 fs after optical excitation.
• Ambident dienophile 57 reacts with DAPC 54 at the cyclobutene π-bond to produce ligand 58; in contrast, the related ambident dienophile 59 reacts with DAPC 54 at the naphthoquinone π-center to produce adduct 60 (lack of shielding of the methylene protons supports the stereochemical assignment).
