The hydrogenation of heptacyclo[8.4.0.0(2,12).0(3,8).0(4,6).0(5,9).0(11,13)]tetradec ane (binor-S) (1) to tetrahydrobinor-S has been carried out in the presence of Pt- and Ni-containing heterogeneous catalysts. The hydrogenation of (1) on Pt catalysts prepared by the reduction of H2PtCl6 with the aid of NaBH4 proceeds in MeOH, EtOH and AcOH under mild conditions (0.1 MPa, 70 degrees C, 36 hr). For a similar reaction under the action of nickel systems (obtained by the precipitation of NiCO3 on supports with subsequent heat treatment in hydrogen at 400 degrees C for 3 hr), harsher conditions are required: 220-240 degrees C, H-2 pressure 8 MPa, 24 hr, hexane. The hydrogenation of (I) produces isomeric C14H20 hydrocarbons (yield 80%), which are the initial feedstock in the synthesis of diamantane (2).
