title: Asymmetric bromine-lithium exchange: on the importance of both the diamine ligand and the organolithium reagent.
abstract: 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.
