摘要：

The new square-planar nickel(II) complexes of o-phenylenebis(N'-methyloxamidate) and related ligands catalyse the aerobic epoxidation of olefins with co-oxidation of pivalaldehyde; the modulation of catalytic activity by substituents along this series of metal complexes points out the role of high-valent nickel(IV)-oxo species as the putative intermediate in these oxygen atom transfer reactions.
