Description

General description

cis-2-Hexene is one of the isomeric forms of hexene. It is obtained from 2-hexyne, via semihydrogenation in the presence of Pd78(phen) [phen = 1,10-Phenanthroline] on titanium dioxide in n-octane. cis-2-Hexene is formed as one of the primary product from the dimerization of propylene in the presence of a nickel oxide-silica-alumina catalyst. It undergoes isomerization/hydrosilylation reaction with phenyl silane in the presence of cobalt catalyst to afford 1-hexylphenylsilane.
