Reactions and applications of titanium imido complexes

This Account highlights aspects of the reactions and applications of titanium imido complexes. Over the past decade in particular, the Ti=NR linkage has been shown to couple stoichiometrically with a variety of unsaturated substrates including CO2, carbodlimides, isocyanates, isocyanides, acetonitrile, phosphaalkynes, alkynes, alkenes, and allenes. Especially recently, there has been much interest in using titanium imides as catalysts for hydroamination and olefin polymerization. The advances in these areas are also reviewed.
