| | BENZENE CHROMIUM TRICARBONYL Usage And Synthesis |
| Chemical Properties | yellow crystalline powder | | Uses | Catalyst for:
- Oxidation of alkenes
- Hydrogenation of alkynes
| | Preparation | For cases where large quantities are needed, benzene chromium tricarbonyl is easily prepared from the reaction of benzene with Hexacarbonylchromium.
| | reaction suitability | core: chromium
reagent type: catalyst | | Solubility in organics |
benzene chromium tricarbonyl is soluble in THF, ether, benzene.
| | Purification Methods | Purify the complex by sublimation in vacuo. A possible impurity is 2-picoline which can be removed by washing with pentane and drying. It is then purified further by sublimation at 80-85o/10-3mm, or by recrystallisation from Et2O to give yellow crystals. 1H NMR in CDCl3 should give a single peak at 4.68.
