Impregnated copper on magnetite as recyclable catalyst for the addition of alkoxy diboron reagents to C-C double bonds.
A simple protocol for the borylation with use of impregnated copper on magnetite is described. The reactions showed a very broad scope and all type of olefins could be used with similar results. The catalyst could be easily removed by a magnet and it could be reused several times, showing similar activity.
