Information on this page: Reaction thermochemistry data; Mass spectrum (electron ionization) References; Notes Activation of the catalysts is found to cause decomposition of the molybdenum hexacarbonyl. C5, 59655 Villeneuve d'Ascq, France Infrared spectroscopy has been used to study the olefin disproportionation catalysts consisting of molybdenum hexacarbonyl supported on silica, alumina and magnesia. The experiment aims to investigate the cis-trans isomerization of Mo(CO) 4 (PPh 3) 2.In order to obtain these compounds, molybdenum hexacarbonyl is first reacted with piperidine (pip), which leads to the formation of cis-Mo(CO) 4 (pip) 2.The ligand exchange with triphenylphosphine at low temperature (40 o C, boiling dichloromethane) affords the cis-Mo(CO) 4 (PPh 3) 2.

Rapid Communication. General description Molybdenumhexacarbonyl is a white crystalline solid, melts at 150 o C, density 1.96 gm/cc, is insoluble in water and soluble in most organic solvents.. The reaction mixture was stirred rapidly under argon atmosphere at room temperature and the progress of the reaction was followed by recording the IR spectra of the aliquots, at different time intervals.
