Air- and Water-Stable Catalysts for Hydroamination/Cyclization. Synthesis and Application of CCC−NHC Pincer Complexes of Rh and Ir
摘要:
The scope of CCC-NHC pincer complex synthetic methodology by metalation/transmetalation has been extended to Ir. Structural characterization revealed that it is isomorphous with the Rh complex. Both Rh and Ir complexes are efficient catalysts for the hydroamination/cyclization of secondary amines in the presence of air and/or water.

CCC–NHC Zr pincer complexes can be generated in situ and transmetallated with an appropriate Rh source to generate CCC–NHC Rh pincer structures. These two methodologies, metallation of CCC–NHC precursors with transitionmetal amido complexes combined with transmetallation, hold great promise for opening general synthetic pathways to a wide variety of transitionmetal CCC–NHC pincer complexes.
