A Highly Enantiomerically Enriched Lithiosilane by Selective Cleavage of a Silicon–Phenyl Bond with Lithium

On the path to chiral polysilanes, the synthesis and first structural characterization of the enantiomerically pure tetrasilane (R)-3 was achieved. A new synthetic strategy was used, by which the cleavage of a silicon–phenyl bond in the substrate (R)-1 generated as intermediate the enantiomerically enriched lithiosilane 2.
