IR LASER PYROLYSIS AND THE ISOTOPIC LABELLING OF ORGANOMETALLIC COMPOUNDS

Article abstract of DOI:10.1016/S0022-328X(00)98693-5

A homogeneous gas phase pyrolysis technique involving SF6 sensitization and a continuous wave (CW) CO2 laser, is described for preparing small quantities (ca. 100 mg) of organometallic compounds.Several reactions have been successfully carried out and the synthesis of Os(CO)5 from H2Os(CO)4 and CO is discussed in detail.With IR laser pyrolysis, room temperature reactors and sub-atmospheric pressures can be used for reactions which normally require high pressures and temperatures.
