Kinetically determined bond dissociation energies in hexamethyldisilane

Abstract

A re-investigation of the thermolysis of hexamethyldisilane gives D(Me₃Si–SiMe₃) as 337 kJ mol^–1(80·5 kcal mol^–1), the Arrhenius A factor for this dissociation being 10^17·53s^–1; D(Me₃Si–H) is estimated is estimated as 368 kJ mol^–1.
