摘要：

Cooperating catalysts: The combined single-site/dispersed-metal catalyst [Rh(cod)(sulphos)]-Pd0/SiO2 (cod= cyclooctadiene; sulphos = -O3S(C6H4)CH2C(CH2 PPh2)3) is more efficient than the dispersed-metal catalyst Pd0/SiO2 for the hydrogenation of arenes to cycloalkanes. The grafted rhodium moieties and the palladium particles in [Rh(cod)(sulphos)]-Pd0/SiO2 cooperate to speed up the hydrogenation of arenes (see scheme).
