摘要：
β-Ketoimine ligands stabilize zinc compounds: The dimeric zinc alkylperoxide [{(LL)ZnOOEt}2] (where LE = HC{(CMe)(2,6-iPr 2C6H3N)}2) has been prepared and structurally characterized (see picture, Zn green, N blue, O red, C gray). This compound, which is formed by the insertion of dioxygen into the Zn-Et bond, is very active in the epoxidation of enones.
