- Mechanistic study of the Diels-Alder reaction of paramagnetic endohedral metallofullerene: reaction of La@C82 with 1,2,3,4,5-pentamethylcyclopentadiene.
Mechanistic study of the Diels-Alder reaction of paramagnetic endohedral metallofullerene: reaction of La@C82 with 1,2,3,4,5-pentamethylcyclopentadiene.
The reaction mechanism of the Diels-Alder reaction of paramagneticendohedral metallofullerene, La@C82, and 1,2,3,4,5-pentamethylcyclopentadiene was studied theoretically and experimentally. Theoretical calculations revealed that this reaction proceeds via a concerted mechanism that includes formation of a stable intermediate. The activation energy of a retro-Diels-Alder reaction was also studied experimentally, which is in good agreement with theoretical results.
