文摘

Mapped on the image of the reactive differential cross section, the hitherto elusive disilavinylidene molecule (H₂SiSi) is found to be initially formed in the gas-phase reaction of ground-state atomic silicon (Si) with silane (SiH₄) and in equilibrium with the mono-bridged (Si(H)SiH) and di-bridged (Si(H₂)Si) isomers. As shown by R. I. Kaiser, A. H. H. Chang, J. F. Stanton et al. in their Communication on page 1264 ff., the dynamics are distinct from those of the isovalent carbon/methane system, and provide a rare glimpse of unusual silicon chemistry.
