Tri-μ-carbonylhexacarbonyldiiron - Reference Information
| EPA chemical substance information | information provided by: ofmpeb.epa.gov (external link) |
| Use | dinonyl carbonyl iron is widely used in tropane, monoketone and its analogs, cyclopentanone, cyclopentenone, synthesis of cycloheptenone, benzocyclobutene and trimethylene methane. |
| production method | 1. Note that l should be operated in the fume hood. A 1-liter three-necked flask equipped with a stirrer, a gas inlet tube and a Mercury bubbler was placed in a 5-liter silver-plated Dewar and cooled with running water, after flushing with nitrogen, 100 (146G, 0.746 mol) of penta-valent iron and 200 of ice vinegar were added and then irradiated with a 125W high-pressure mercury lamp. In order to avoid contact of the cooling water with the permanent lamp, the irradiation system is made of a quartz tube (about 30cm in length and about 1.7cm in inner diameter). One end of the pipe is closed, and a 125 watt mercury vapor bulb is connected to it, and the connecting line is insulated by a porcelain ring. The quartz tube was placed in the water inside the Dewar and r was as close as possible to the reaction vial. In order to avoid a decrease in light intensity due to the deposition of the product in the reactor, the reaction mixture should be stirred effectively. If the product is deposited in the wall, the reaction may be interrupted from time to time to remove the nine-divalent diiron produced. The sediment was flushed with nitrogen several times and then returned to the reaction flask. After 24 hours (note), nine carbonyl two iron was filtered, washed with ethanol, ether sequentially, and vacuum dried to obtain 100 to 122 grams (74 to 91% product. When the Dewar bottle was not capped, the yield was only 74%; When both the plastic barrel and the cover of the Dewar bottle were lined with aluminum foil, the yield was as high as 91%. |
