title: The rate of elimination of a beta-amino zinc reagent is reduced by using a better leaving group.
abstract: Replacing the N-Boc-protecting group on a beta-amino organo-zinc reagent with a trifluoroacetyl group, which would be expected to make the nitrogen a better leaving group, results in a reagent that is more stable towards elimination.
