Mobility of Lewis acids within the secondary coordination sphere: toward a model for cooperative substrate binding

Abstract

Distance dependence of appended Lewis acids in N₂H₄ binding and deprotonation was evaluated within a series of zinc complexes. Variation of spacer-length to a tethered trialkylborane Lewis acid revealed distinct preferences for binding and stabilization of the resulting deprotonated N₂H₃⁻ unit.
