Cyclohexadecadienes

Production of fragrances Symrise cyclooctene cyclohexadecenone (Globanone) via cyclohexadecadiene Ruthenium based catalysts 25-100°C... 

Of course, in this reaction of cyclic olefins, the reaction does not necessarily stop at the first step, but proceeds further to form trimer, tetramer, and polymers by sequential metathesis reactions. For example, Wideman carried out the metathesis of cyclooctene and obtained 1,9-cyclohexadecadiene in 20% yield, from which 16-membered monoketone and diketone were synthesized, 61>.
