Commercially available Raneycobalt is broadly applicable as a catalyst in intra- and intermolecular Pauson–Khand reactions (PKR). The activity of Raneycobalt compares favourably with that of previously described heterogeneous or heterogenised cobalt systems. The major reaction pathway appears to occur at the solid catalyst which can be efficiently separated and reused by filtration and/or exploiting
