Abstract
Cyclopentadienyl manganese tricarbonyl compounds are made by reacting a mixture of 0.25-0.55 moles of manganese acetate and 0.45-0.55 moles of a bis-cyclopentadienyl manganese compound with about 0.5-2.1 moles of an alkyl aluminum compound (e.g. triethyl aluminum) in the presence of about 0.75-1.25 moles of an ether per mole of said alkyl aluminum compound and reacting the mixture with carbon monoxide at about 65.degree.-175.degree. C. and 300-1500 psig.
