Heterochiral Triangulo Nickel Complex as Evidence of a Large Positive Nonlinear Effect in Catalysis
dataset
posted on 2008-02-04, 00:00 authored by John S. Fossey, Ryosuke Matsubara, Hiroshi Kiyohara, Shū KobayashiA novel triangulo complex was generated by heating, in vacuo, a
racemic C2-symmetric octahedral nickel(II) diamine complex. The
trinuclear species was identified by single-crystal X-ray diffraction,
which revealed a 2:1 ligand stereochemistry relationship in each
unit. This solid-state structure evidences the hypothesis that a 1:2
stereochemical relationship lies at the heart of the strong positive
nonlinear effect observed in enecarbamate aldol-like reactions
catalyzed by nickel(II) diamine complexes.
