Previously, molybdenum hexacarbonyl, MO(CO)6 has been prepared by reduction of highoxidation state molybdenum compounds such as MoCls under high pressure (60-100atm.) and temperature (20-1000C), carbonylation of metal oxide at very high pressure(2000 atm) and temperature (3000C) or carbonylation of the metal itself at 250 atmpressure and 200°C. Products made under these conditions are very expensive. The present study was aimed at investigating whether MO(CO)6 can be prepared under mild conditions by reducing trihalotris (tetrahydrofuran) molybdenum(III), Mo(THF)3X3(X=Cl, Br) with zinc dust at 1 to 2 atmospheres. The results confirm beyond any reasonable doubt that this is possible. Products were isolated using thin layer and column chromatography, and identified using infrared spectroscopy and elemental analysis.
