  The Mercury-Photosensitized Decomposition of Hexamethyldisilane

  摘要：

  AbstractThe kinetics and mechanism of the mercury‐photosensitized decomposition of hexamethyldisilane have been studied. It has been confirmed that the initially‐formed radical, Me3SiSi(Me2)CH2, undergoes a unimolecular rearrangement; Arrhenius parameters have been measured for this rearrangement and for subsequent reactions of the rearranged radical:magnified imageThe significance of these Arrhenius parameters in silicon chemistry is discussed by means of thermochemical calculations.
