The cationic ruthenium arene complex, [RuH(PPh3)2(eta-6-9,10-dimethylanthracene)]+ (1), serves as a catalyst for the hydrogenation of 9,10-dimethylanthracene (2), initially to 1,2-dihydro-9,10-dimethylanthracene (3), followed by hydrogenation of the latter to 1,2,3,4-tetrahydro-9,10-dimethylanthracene (4). The first step, i.e., 2 --> 3, obeys the rate-law -d[2]/dt = k(cat)[1][H2], where k(cat) = (1.5 +/- 0.1) x 10(-3) M-1 s-1 at 25-degrees-C in CDCl3.
