Conclusions

  1. 1.

    At 425–500°, 1,2,4,5,5-pentamethylcyclopentadiene smoothly isomerizes into 1,2,3,4,5-pentamethyl-cyclopentadiene as a result of 1,3-migration of the methyl group in the cyclopentadiene ring.

     
  2. 2.

    The mechanism proposed for this isomerization is the combination of two consecutive acts of 1,2-migration of the methyl group.
