Catalytic hydrogenation of 9H-fluorene (1), phenanthrene (2), 4H-cyclopenta[def ]phenanthrene (3), pyrene (4), and fluoranthene (5) was carried out over Raney nickel (W-7) at 323 K under 608 kPa of hydrogen. The order of the reaction rate was 5 > 4 > 3 > 2 > 1. The adsorption equilibrium constant of the substrates decreased in the order 4 ≥ 5 >> 2 > 3 >> 1.
