Kinetics of the reaction of silylene with hydrogen and a possible resolution of discrepancies over ΔHf⊖(SiH2)
Abstract
RRKM (Rice–Ramsperger–Kassel–Marcus) calculations, carried out to fit some new experimental data, are found to reconcile apparent differences in two recent studies of the fast reaction between SiH2 and H2: the calculations lead to ΔHf⊖(SiH2)= 65.3 ± 1.5 kcal mol–1.
