The effect of the metal particle size and the modifier concentration on the enantioselectivity (ee) and the conversion level in the hydrogenation of three different substrates: 1-phenyl-1,2-propanedione, ethyl pyruvate and acetophenone were studied over Ir/SiO 2 catalysts. The metal loading was vari
