C-C bond formation catalyzed heterogeneously by nickel-on-graphite (Ni/Cg).
Inexpensive nickel(II) mounted on graphite (Ni/Cg) can be easily activated and used to heterogeneously catalyze cross-couplings involving aryl halides/tosylates with boronic acids, vinylalanes, and vinylzirconocenes. Comparisons are made with the charcoal analogue, Ni/C, and some unusual chemoselectivities between these catalysts have been uncovered.
