1,2,3,4,5-Pentamethylcyclopentadiene Chemical Properties,Uses,Production

Chemical Properties

clear colorless to yellowish liquid

Uses

1,2,3,4,5-Pentamethylcyclopentadiene serves as a precursor to the ligand 1,2,3,4,5-pentamethylcyclopentadienyl. It is used as a growth modifier chemical, during metal organic chemical vapor deposition of iron from iron pentacarbonyl. It is used as a ligand in "one-pot" iridium-catalyzed transformation of alcohols to amides. Further, it acts as an electron mediator in the regeneration process of nicotinamide adenine dinucleotide. In addition to this, it undergoes radical cation catalyzed cycloaddition reaction with allenes to get Diels-Alder product.

General Description

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.
