competing reactions from the same catalyst—a composite catalytic‐complex@catalytic‐metal—is reported. A Wilkinson rhodium based catalyst entrapped within metallic palladium catalyst is shown to perform both hydroformylation and hydrogenation with a ratio that depends on H2 and CO pressures. Here we demonstrate this special reactivity in a one‐pot, fourstep sequence, which include hydroformylations of phenyl
The hydroaminomethylation of arylethylenes with anilines proceeds under mild conditions in the presence of [Rh(cod)(2)BF4] and dppf as catalyst system to give the corresponding branched amphetamine derivatives in good selectivity and yield. (c) 2005 Elsevier Ltd. All rights reserved.
