Rhodium

The rhodium catalyst has been shown to be suitable promoter for the activation of C-H bonds, which has emerged as a challenging and attractive tool for catalysis. Rhodium catalysis finds increasing interest in the catalytic dehydrogenative cross-coupling, allowing elegant C-C bond construction. Although palladium has been the metal of choice for most examples, Rh catalysts can be suitable promoters for this activation. By using rhodium catalysts from Sigma-Aldrich, access is gained to important couplings such as aryl-aryl, aryl-alkene, and alkene-alkene, viable routes to valuable organic frameworks.
