• synthetische

  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%.

• Allgemeine Beschreibung

  Methylcyclopentadienyl manganese tricarbonyl (hereinafter "MMT") is an antiknock agent for gasoline discovered in the fifties and sold commercially by Ethyl Corporation. It can be made by the reaction of carbon monoxide with bis(methylcyclopentadienyl) manganese referred to as "carbonylation".
