| abstract |
The present invention relates to a catalyst system comprising a transition metal compound on a solid carrier which is a "surface-reacted calcium carbonate" comprising calcium carbonate and a water-insoluble calcium salt other than calcium carbonate, such as hydroxylapatite. The invention further relates to a method for manufacturing said catalyst system and to its use in heterogeneous catalysis, especially in C-C cross couplings and glycerol hydrogenolysis. |
