Title
Polystyrene-supported poly(amidoamine) dendrimer–manganese complex: Synthesis, characterization and catalysis
Abstract

A novel polymer-supported heterogeneous oxidation catalyst is reported. Manganese complexes of polystyrene-supported poly(amidoamine) dendrimer were prepared, characterized and used as catalysts for oxidation of secondary alcohols. The catalysts showed high stability and efficiency under various reaction conditions and with different substrates. The catalysts can be recycled.

Graphical abstractManganese complexes of polystyrene-supported poly(amidoamine) dendrimers of three generations (G1–G3) were prepared and characterized. These complexes were found to be efficient and reusable catalysts for the oxidation of secondary alcohols to ketones under mild reaction conditions. The catalyst remained stable under different reaction conditions and with various substrates. A positive dendrimer effect was observed. Oxidation was efficient in the presence of a green oxidant like urea–hydrogen peroxide adduct. The catalyst can be recycled up to six times.Figure optionsDownload full-size imageDownload as PowerPoint slide
