Rhodium(iii) vs. cobalt(iii): a mechanistically distinct three-component C–H bond addition cascade using a Cp*RhIII catalyst†
Abstract
Three-component C–H bond additions across two different coupling partners remain underdeveloped. Herein, we report the first three-component RhIII-catalyzed C–H bond additions to a wide range of dienes and aldehydes. Our method constitutes a complementary access with Ellman's CoIII-catalytic system to homoallylic alcohols.
