For the hydrogenatlon of aromatic nitrocompounds, PdCl2 (TPPTS)2-H2PtCl6 ex-hibited much higher catalytic activity than that of PdCl2(TPPTS)2 or H2PtCl6. The synergic effect can also be observed even if the composition of Pt was 2% (molar ratio). A high selec-tivity for the chloroaniline was obtained in the hydrogenation of nitrochlorobenzene catalyzed by PdCl2 (TPPTS)2 and bimetallic catalyst PdCl2 (TPPTS)2-H2PtCl6.
