资源简介：
An axially chiral,
cyclic borane decorated with just one C6F5 group
at the boron atom promotes the highly
enantioselective hydrosilylation of acetophenone derivatives without
assistance of an additional Lewis base (up to 99% ee). The reaction
is an unprecedented asymmetric variant of Piers’ B(C6F5)3-catalyzed carbonyl hydrosilylation. The
steric congestion imparted by the 3,3′-disubstituted binaphthyl
backbone of the borane catalyst as well as the use of reactive trihydrosilanes
as reducing agents are keys to success.
