BENZENE CHROMIUM TRICARBONYL 화학적 특성, 용도, 생산

• 화학적 성질

  yellow crystalline powder

• 용도

  Catalyst for:
  
  • Oxidation of alkenes
  • Hydrogenation of alkynes

• 제조 방법

  For cases where large quantities are needed, benzene chromium tricarbonyl is easily prepared from the reaction of benzene with Hexacarbonylchromium.

• 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.
