Abstract:
A kinetic investigation of the gas-phase isomerisation of hexamethyldisilane between 717 and
780 K with initial pressures of 10-125 mmHg is described, and discussed in relation to other work on
the thermolysis of hexamethyldisilane. The isomerisation is a radical chain reaction of three halves
order, with rate constants given by Xr/cmJ moH s-' = iol6-6s±o-7O exp[— (251 ± 8)/2?T] (activation
energy in kJ mol-1).
