Abstract

The heteronuclear complexes [(CO)₄Fe(μ-PPh₂)Pd(μ-Cl)₂]₂, [Et₄N] [FeCo₃(CO)₁₂] and Rh₂Co₂(CO)₁₂ were physically entrapped in SiO₂-sol-gel matrices. The doped materials, so formed, were utilized as recyclable catalysts for (a) selective isomerization of 1-octene, (b) selective dimerization of norbornadiene to 'binor-S', and (c) hydrogenation and hydrogenolysis of styrene, nitrobenzene and 1-chloronaphthalene, respectively. During the hydrogenation of the nitrobenzene and of chloronaphthalene, the dodecacarbonylbis(cobalt)dirhodium was converted into sol-gel entrapped carbonyl-free nanoparticles that efficiently catalyze the reduction of the aromatic C-C bonds.
