일반 설명
Mechanism of the Diels-Alder reaction of paramagneticendohedral metallofullerene and 1,2,3,4,5-pentamethylcyclopentadiene has been studied. Three-step large-scale preparation of 1,2,3,4,5-pentamethylcyclopentadiene has been reported. Reaction of 1,2,3,4,5-pentamethylcyclopentadiene (HCp*) with actinide ions in gas phase has been investigated by laser ablation mass spectrometry. It undergoes radical cation catalyzed cycloaddition with electron rich allenes to form Diels-Alder product.
애플리케이션
1,2,3,4,5-pentamethylcyclopentadiene was used as:
- Growth modifier chemical, during metal organic chemical vapour deposition of iron from iron pentacarbonyl.
- Ligand in "one-pot" iridium-catalyzed transformation of alcohols to amides via the intermediacy of oximes.
- Raw material for the synthesis of [Cp*Rh(bpy)H2O]2+ (Cp* = pentamethylcyclopentadienyl, bpy = 2,2′-bipyridyl), an electron mediator in the regeneration process of NADH.

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

The Diels–Alder reaction is the reaction between a conjugated diene and an alkene (dienophile) to form unsaturated six-membered rings. It is also referred to as a cycloaddition.
