✦ Synopsis

The epoxidation of linear and cyclic olefins was catalysed by iron( III), nickel(II) and cobalt(I1) centres immobilized on insoluble polymers. The latter were obtained by reaction of the polymerizable complexes of Fe( III), Ni( II) and Co( II) with 2-(acetoacetoxy)etbyl metbacrylate with acrylamides.

Aromatic a-hydroxyketones were easily oxidized by dioxygen in the presence of excess aldehyde or aldoacetal with catalytic amount of Co(II) or Fe(II1) complexes, under homogeneous and heterogeneous conditions. Co(acac), or Fe(acac), were the catalysts used in homogeneous phase reactions whereas Co(I
