Mechanism and an Improved Asymmetric Allylboration of Ketones Catalyzed by Chiral Biphenols

Giving it a boost: A mechanistic study of the enantioselective asymmetric titled reaction with allyldiisopropoxyborane catalyzed by chiral biphenols revealed a key ligand exchange process which liberates isopropyl alcohol. The addition of iPrOH to the reaction increases the overall rate and enantios...
