Abstract:
1. A method for producing alkylated cyclopentadienyl manganese tricarbonyls, comprising the steps of: (1) selecting a reaction kettle with a stirring device, a heating devise, and a reaction solvent medium in which a reaction occurs in an inert gas atmosphere; (2) injecting required amounts of reaction solvent medium and metal sodium into the kettle, so that the reaction process occurs in the inert gas atmosphere; (3) adding alkylated cyclopentadiene into the kettle to form a reaction mixture; (4) stirring the reaction mixture, wherein a halt in the release of hydrogen indicates that the reaction is complete and that alkylated cyclopentadienyl sodium has been produced; (5) at room temperature, adding into the kettle manganese chloride and iron sulfonate dicarbonyl or iron phosphonate dicarbonyl, stirring and eating, then filling the kettle with CO, pressurizing the kettle to at least 80-100 atm with CO, heating the reaction mixture to a temperature sufficient to complete the reaction, (6) when CO is no longer absorbed, which indicates that the reaction process is completed, stopping the heating, continuing to stir while cooling to room temperature, unloading the reaction mixture from the reaction kettle and obtaining a raw product.
