Asymmetric silyllithium reagents

The formation of an asymmetric silyllithium reagent by lithium cleavage of the silicon-silicon bond of an optically active disilane 10 (eq. [7]) has been reported (26). Hydrolysis of the silyllithium reagent 11 yielded an optically active silicon hydride. This result demonstrates that silyllithium has considerably enhanced optical stability relative to acyclic alkyllithium compounds. 

The formation of an asymmetric silyllithium reagent from an optically active disilane has been reported92 (equation 25).
