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.
