Immobilized Cobalt/Rhodium Heterobimetallic Nanoparticle-Catalyzed Silylcarbocylization and Carbonylative Silylcarbocyclization of 1,6-Enynes

Immobilized Cobalt/Rhodium Heterobimetallic Nanoparticle-Catalyzed Silylcarbocylization and Carbonylative Silylcarbocyclization of 1,6-Enynes

Reaction of 1,6-enynes with a hydrosilane in the presence of immobilized cobalt/rhodium bimetallic nanoparticles gives 2-methyl-1-silylmethylidene-2-cyclopentanes in the absence of carbon monoxide and 2-formylmethyl-1-silylmethylidene-2-cyclopentanes under 1 atm of carbon monoxide, respectively.
