1-Octadecene is a long-chain hydrocarbon and an alkene with the molecular formula CH₂=CH(CH₂)₁₅CH₃. It is one of many isomers of octadecene. Classified as an alpha-olefin, 1-octadecene is the longest alkene that is liquid at room temperature.^[3]^[2]

Hydrosilation

Treatment of 1-octadecene with trichlorosilane in the presence of platinum catalysts gives octadecyltrichlorosilane. Octadecene adds to hydrogen-terminated bulk silicon.^[4]
