Beschreibung

Anwendung

2-Methyl-2-butene can be used:

• For the cross metathesis reaction to form compounds with prenyl-type double bonds: methyl 10-methylundec-9-enoate, 2-methylundec-2-ene and 8-prenylcoumarins.
• As a model of C5-branched alkene fuel to study the high-temperature kinetics of branched alkenes in a combustion environment.
• As an additive along with pyridine for partial hydrogenation of poly-ynes to form ω-hydroxy polyunsaturated fatty acids.
