reaction suitability

core: molybdenum
reagent type: catalyst

Synthesis

Tricarbonyl(Η-cyclopentadienyl)manganese dimerization was prepared as follows: tetrahydrofuran (THF, 45 ml) was added to 18.8 mmol of cyclopentadiene, and after cooling to -78 ??C, 12.5 ml (18.8 mmol) of Bu-Li was added drop-wise, and pentamethylcyclopentadienyl lithium was coordinated. Then 5 g (18.8 mmol) of molybdenum hexacarbonyl was added to the substance and heated at reflux for 48 hours, and when the reaction was complete, the mother liquor was cooled to 0 ??C. Separately, 3.2 g (18.8 mmol) of ferrous sulfate (II) was added to a solution comprising a mixture of 100 ml of pure water and 20 ml of acetic acid, and the solution so obtained was added dropwise to the mother liquor. The resulting red solution was made to undergo suction filtration, washing and drying, and the manganese tricarbonyl (Η-cyclopentadienyl)-co-manganese dimer complex was obtained by recrystallization. The yield was 20%.
