General description

1,7-Octadiene can serve as a crosslinker and source of ethylene for a variant of Mori′s conditions in CEYM-related reactions.

Application

1,7-Octadiene has been used in a study to assess the structure and reaction rate in olefin ring-closing metathesis of a series of simple dienes. It has also been used in a study to investigate micropatterned surfaces prepared by plasma polymerization.

In the RCM reactions of a series of simple α,ω-dienes, the relative order of reactivity has been unambiguously determined showing that cyclohexene forms faster than cyclopentene or cycloheptene. 1,5-Hexadiene inhibits the RCM of 1,7-octadiene; 1,5-hexadiene cannot progress to the RCM
