Abstract
Co-pyrolyses of disilane with monosilane or with hydrogen have been conducted over wide ranges to temperature, pressure and mixture composition. The following Arrhenius parameters for the silene insertion reactions have been calculated from the rate data and thermochemical information: SiH2+ SiH4→ Si2 H6(– 1), SiH2+ Si2H6→ Si3 H8(2), SiH2+ H2→ SiH4(5), log(A–1/l. mol–1 s–1)= 9.7, E–1= 5400 J mol–1; log(A2/l. mol–1 s–1)= 9.85, E2= 1615 J mol–1; log(A5/l. mol–1 s–1)= 9.1; E5= 23 000 J mol–1.Disilane is shown to be a suitable source of silene and the data presented for k2 and E2 now permit extension of the co-pyrolysis method to the evaluation of the rate parameters of a range of other silene insertion reactions.
