Abstract

Abstract The organic oxidant TEMPO (2, 2, 4, 4-tetramethylpiperdine-1-oxyl) was immobilized on iron oxide (Fe 3 O 4) superparamagnetic nanoparticles by employing strong metal-oxide chelating phosphonates and azide/alkyne “click” chemistry. This simple preparation yields recyclable TEMPO-coated nanoparticles with good TEMPO loadings. They have excellent magnetic response and efficiently catalyze the oxidation of a wide ...
