| Abstract | The previously described chelating N-heterocyclic carbenes (NHCs) were designed as electron-rich analogs to the salicylaldimine (sal) ligands featured on our neutral Ni catalysts for olefin polymerization. As part of our thorough investigation, we decided to target chelating NHCs to serve as analogs to the diimine ligands featured on Brookhart’s cationic Ni and Pd catalysts. 1 Pursuant to this goal, a bidentate NHC/imine ligand was synthesized. This compound was demonstrated to be a competent ligand for transition metals in the synthesis of a Ag carbene. Although the attempted ligation to group 10 metals led only to ligand decomposition, the new compounds show promise as ligands. 130 As discussed in Chapter 1, the two major developments in late metal-catalyzed olefin polymerization were the discovery of neutral Ni catalysts by our group 2 and |
