Iridium–Bismuth cluster complexes yield bimetallic nano-catalysts for the direct oxidation of 3-picoline to niacin
Iridium–Bismuth cluster complexes yield bimetallic nano-catalysts for the direct oxidation of 3-picoline to niacin
The reaction of Ir3(CO)9(?3-Bi), 1, with BiPh3 has yielded a iridium–bismuth cluster complex Ir5(CO)10(?3-Bi)2(?4-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.

Abstract
The reaction of Ir3(CO)9(?3-Bi), 1, with BiPh3 has yielded a iridium–bismuth cluster complex Ir5(CO)10(?3-Bi)2(?4-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.
