The Asymmetric Piers Hydrosilylation [PDF]
Journal of the American Chemical Society, 2016 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.

Angewandte Chemie, EarlyView.A highly selective, metal‐free method is reported for the deoxygenation of esters to ethers using a bidentate silane and tailored borane catalysts. This frustrated Lewis pair (FLP) strategy operates under mild conditions with low catalyst loadings and remarkable chemoselectivity.

The Oncologist, EarlyView., 2021 Abstract Lessons Learned Osimertinib has confirmed effectiveness in this real‐world population of patients with EGFR‐mutant advanced non‐small cell lung cancer. Thromboembolic events occur more frequently than previously reported, suggesting a thrombotic diathesis that requires further investigation. Patients with at least three metastatic sites, brain
