The advantages of homogeneous and heterogeneous catalytic systems are combined in stationary liquid‐phase catalysts such as the system [PtCl 2 ,(CH 3 CN) 2 ] in BF 3 · H 2 O on clay or silica supports, which is used here for hydrogenation of arenes. The hydrogenation can be performed under relatively mild conditions, the products are separable by simple filtration, and the hydrogenation proceeds selectively, as shown for a 1 : 1 : 1 : 1 mixture of benzene, toluene, o ‐xylene, and 1,2,4‐trimethylbenzene.
