Novel weak coordination to silylium ions: formation of nearly linear Si-H-Si bonds.
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.
