Asymmetric hydrosilylation of alkenes with alkoxyhydrosilanes catalyzed by chiral bis(oxazolinyl)phenyl-rhodium complex

Asymmetric addition of alkoxyhydrosilanes to styrene derivatives was examined with chiral bis(oxazolinyl)phenyl-rhodium complex to give moderate ratios (up to 77:23) of alpha- and beta-adducts and high enantioselectivity (up to 95% for the alpha-adduct).
