Various optically active silicon compounds have been synthesized or separated, and used to synthesize silicon-containing polymers with well-controlled stereochemical structures. Hydrosilylation, anionic ring-opening polymerization and cross-coupling reactions have been used to synthesize optically active and/or stereoregular silicon-containing polymers.

TLDR
An unprecedented copper-catalyzed desymmetrizing protoboration of divinyl substituted silanes with bis(pinacolato)diboron (B 2 pin 2) allows facile preparation of an array of enantiomerically enriched boronate-substituted organosilanes bearing contiguous silicon- and carbon-stereocenters with exclusive regioselectivity and generally excellent diastereo- and enantioselectivities.
