For example, 3, 4-dimethyl-1, 5-hexadiene heated to 300 �C yields 2, 6-octadiene.

The telomerization of butadiene with methanol in the presence of a palladium catalyst yields 1-methoxy-2, 7-octadiene, which is fully hydrogenated to 1-methoxyoctane in the next step.
3.
The Nicolaou group therefore sought to synthesize endiandric acid C from an acyclic symmetric diacetylenic diol precursor, "'14 "'( as shown ); they began with " mild hydrogenation " in the presence of Lindlar catalyst and quinoline, anticipating tetraene diol "'15 "', cyclooctatriene "'16 "', or the fully cyclized bicyclo [ 4.2 . 0 ] octadiene ( bicyclic diol ) "'17 " '.
