Application
- For the cross metathesis reaction to form compounds with prenyl-type double bonds: methyl 10-methylundec-9-enoate, 2-methylundec-2-ene[1] and 8-prenylcoumarins.[2]
- As a model of C5-branched alkene fuel to study the high-temperature kinetics of branched alkenes in a combustion environment.[3]
- As an additive along with pyridine for partial hydrogenation of poly-ynes to form ω-hydroxy polyunsaturated fatty acids.[4]
