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 href="https://doi.org/10.1002/anie.201611107" rel="references:https://doi.org/10.1002/anie.201611107">page 1264 ff., the dynamics are distinct from those of the isovalent carbon/methane system, and provide a rare glimpse of unusual silicon chemistry.
