Abstract

The reaction of Ir3(CO)93-Bi), 1, with BiPh3 has yielded a iridium-bismuth cluster complex Ir 5(CO)103-Bi)24- Bi), 2. The first examples of bimetallic iridium-bismuth nanoparticles have been subsequently synthesized from 1 and 2, and these have been securely anchored onto the inner walls of mesoporous silica. These isolated, bimetallic iridium-bismuth nanoparticles display a superior catalytic performance, when compared to their analogous monometallic counterparts and equivalent physical mixtures, in the C-H activation of 3-picoline to yield niacin.
