Synthesis, characterization and catalytic activity of Fe(III) complexes containing Schiff base and triphenylphosphine ligands

The oxidation of alcohols to carbonyls was investigated by an efficient catalyst system comprising of Fe(III)–Schiff base–triphenylphosphine complex. The complex chloroN-(2-mercaptophenyl)salicylideneiminebis(triphenylphosphine)iron(III) showed higher activity for oxidation of various alcohols under relatively mild conditions.

Graphical AbstractFe(III)-Schiff base complexes with triphenylphosphine were effective in the oxidation of primary and secondary alcohols in acetonitrile–periodic acid system.Figure optionsDownload as PowerPoint slide
