Slightly soluble in water.

Toxic by ingestion, inhalation, and skinabsorption. Central nervous system impairment;lung, liver and kidney damage。

In concentrated form this compound is highly toxic by all routes of exposure. Approximately 5-15 ml, when spilled on the hand and wrist of a worker, produced toxic effects within 3-5 minutes.

MMT is used as an octane improver in unleaded gasoline, other distillate fuels, and fuel oils; as a smoke abater in fuels.

When heated to decomposition, this compound emits toxic fumes of carbon monoxide. Hazardous polymerization may not occur.

If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medical attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit

Methylcyclopentadienyl manganese tricarbonyl is generally used as an anti-knock agent for gasoline, to increase the octane number of gasoline, thereby preventing engine detonation and improving combustion efficiency. Additionally, it can be used industrially as an organic synthesis catalyst, a precursor in chemical vapor deposition methods for preparing high-performance films, and in laboratory research for doping semiconductor nanocrystals (such as ZnSe) to study their material properties.

Methylcyclopentadienyl Manganese Tricarbonyl is a dark orange liquid with a faintly pleasant odor. It is used as a fuel additive to abate smoke and as a gasolinc additive in antiknock mixes.

Into a reaction flask under nitrogen was placed 1.26 parts bis(methylcyclopentadienyl) manganese (91.8% pure), 0.93 parts manganous acetate, 0.78 parts tetrahydrofuran (THF) and 17.31 parts toluene. Over a period of 15 minutes, a solution of 1.24 parts triethyl aluminum (TEA) in 8.70 parts of toluene was added to the above mixture with a vigorous stirring (Al/Mn atom ratio 1/1, TEA/THF mole ratio 1/1). The solution darkened slightly. This solution of the intermediate complex was transferred under nitrogen to a stainless steel autoclave. The autoclave was sealed, pressurized twice to 300 psig with carbon monoxide and vented and finally pressurized with carbon monoxide to 600 psig and heated while stirring to 100° C. Carbon monoxide was added as needed to maintain 600 psig. After two hours at 100° C., the temperature was raised to 150° C. for 30 minutes. The autoclave was then cooled, vented and discharged. The mixture was hydrolyzed with 10% aqueous HCl. An equal volume of pentane was added to extract the MMT. The pentane phase was analyzed by gas chromoatograph (GC) using a pentadecane internal standard to show a yield of Methylcyclopentadienyl manganese tricarbonyl(MMT) based on manganese of 84% and, based on MCP, of 89%.
