Homogeneous and Heterogeneous Catalysis Using Base Metals From Groups 10 And 11
Recent developments on the use of nickel-in-charcoal (Ni/C) as a catalyst for several cross-couplings assisted by microwave irradiation are presented. The new reagent for synthesis, nickel-on-graphite (Ni/Cg) is presented as a means of catalyzing the reductions of aryl tosylates and mesylates. Another reagent under development, copper-in-charcoal (Cu/C) is described and its potential to effect heterogeneous asymmetric hydrosilylations in the presence of an inexpensive silane is disclosed.
