title: Cyclohydrocarbonylation of substituted alkynes and tandem cyclohydrocarbonylation-CO insertion of alpha-keto alkynes catalyzed by immobilized Co-Rh heterobimetallic nanoparticles.
abstract: The use of cobalt-rhodium (Co(2)Rh(2)) heterobimetallic nanoparticles in the cyclohydrocarbonylation of substituted alkynes and tandem cyclohydrocarbonylation-CO insertion of alpha-keto alkynes to give 2(3H)- or 2(5H)-furanones is described.
