Novel weak coordination to silylium ions: formation of nearly linear Si–H–Si bonds
Stephan P. Hoffmann, Tsuyoshi Kato, Fook S. Tham and Christopher A. Reed
The weakly coordinating carborane anion in ion-like trialkylsilyl species R3Si(CHB11Cl11) can be displaced by nucleophiles as weak as ortho-dichlorobenzene, SO2 and trialkylsilanes, the latter forming nearly linear hydride bridges in R3Si–H–SiR3+ cations.
