Published: December 2015

The asymmetric bromine-lithium exchange on a series of prochiral biphenyls was investigated. As in many asymmetric organolithium reactions, the chiral ligand (here a diamine) was considered to be the enantiocontrolling element. We show here that the organolithium reagent also plays an important role.
