title: (S)-1,2-Dimethyl-1,1,2-triphenyl-2-(4-piperidiniometh-yl)disilane chloride.
abstract: The title compound, C(26)H(34)NSi(2) (+)·Cl(-), shows chirality at silicon. Because of its highly selective synthesis with an e.r. of >99:1 by means of a racemic resolution with mandelic acid, the free disilane is of great importance to the chemistry of highly enanti-omerically enriched lithio-silanes and their trapping products. N-H⋯Cl hydrogen bonding is present between the protonated nitro-gen atom of the piperidino group and the chloride counter-anion. The silicon-silicon distance as well as silicon-carbon and carbon-nitro-gen bond lengths are in the same ranges as in other quaternary, functionalized di- and tetra-silanes.
