General description

Methylcyclopentadienyl manganese tricarbonyl (MMT) is commonly used as an antiknock agent in gasoline. It is also used as an additive in unleaded gasoline.

Application

Methylcyclopentadienyl manganese tricarbonyl can be used for doping of ZnSe nanocrystals.
It can also be used as a reactant for:
  • Aldol addition reactions.
  • Preparation of homo- and heteronuclear mixed biscarbene complexes with conjugated bithiophene units.
  • Molecular fragmentation using shaped femtosecond laser pulses.
  • Preparation of MnAs thin films grown on GaAs(001) by metalorganic vapour phase epitaxy (MOVPE).
