N-heterocyclic carbenes (NHCs), known for their use as ligand scaffolds in late metal catalysis, pose an interesting challenge for high valent early transition metals. NHCs often have labile interactions with group 4 metals because of unfavorable hard-soft interactions; however, modified NHCs can form complexes that have shown promise as catalysts for polymerization and organic transformations. One approach to synthesizing an early-metal NHC complex is the use of an anionic, chelating NHC. We report a monoanionic bis(NHC)borate coordinated to a titanium(IV) imido complex. From this complex, we have synthesized various derivatives and are exploring their modes of reactivity.
