    • The C 1s XPS spectrum measured at hv = 330 eV (not shown) can be fitted with two peaks at 284.8 eV (85% of the spectral weight) and at 286.5 eV (15% of the spectral weight). The broad main peak (1.4 eV fwhm) accounts for the two energetically close structures placed at 284.4 eV (0.86 eV fwhm and spectral weight of 31%) and 285.1 eV (0.95 eV fwhm and spectral weight of 64%) in ref 5. Note that in the present case the high binding peak has a larger spectral weight than the corresponding one placed at 286.8 eV (spectral weight of 5%) in ref 5. As for the N 1s spectrum, the spectral lines are peaked at nearly the same energy in both works and only the relative intensities differ, due to a different distribution of the products.

    • -2. Considering that the adsorption site of 3-butenenitrile comprises two silicon dimers (see section III.C), the sticking coefficient of 3-butenenitrile is ∼0.6 (if the adsorption rate of 2-butenenitrile is negligible). It would be ∼0.3 if the adsorption rate of 2-butenenirile is assumed to be equal to that of 3-butenenitrile.

    • C-Si* transition is seen at 285.6 eV [Matsui, F.; Yeom, H. W.; Matsuada, I.; Ohta, T. Phys. Rev. B 2000, 62, 5036]. In the present case, we therefore expect transitions at 284.5 eV (respectively 285.6 eV) for the unreacted (respectively reacted) vinyl moiety. During the C 1s NEXAFS measurement, the absorption features expected around hv = 285 eV were weak compared to the monochromator transmission "dip" at hv = 284.7 eV (due to the presence of graphitic carbon on the optics), so that the normalization procedure (see section II.A) could not be carried out properly.

    • The calculations of 2-propenenitrile reaction paths, using silicon clusters in Mui et al. (ref 10) and embedded clusters in Choi and Gordon (Choi, C. H.; Gordon, M. S. J. Am. Chem. Soc. 2002, 124, 6162), suggest that di-σ cyano bonding is more favorable kinetically than di-σ vinyl bonding.
