The capability of benz[e]indenyl and benz[f]indenyl ligands to undergo η5-to-η3 haptotropic rearrangement was evidenced on new molybdenum compounds.
Different synthetic strategies towards possibly photoswitchable bis-zirconocenes are discussed. UV-vis spectroscopic and olefin polymerization reactivity studies are described.
Synthesis and characterization of NHC-ligated alanes with one or two indenyl and fluorenyl substituents is presented. These compounds eliminate indene or fluorene upon heating resulting in dimeric or trimeric Al2C, Al2C2 and Al3C3 ring systems.
Carbodiimides undergo 1,2-insertion into 1-metalllacyclobuta-2,3-diene complexes, followed by silyl group migration, the nature of which depends on the carbodiimide substrate.
Planer chiral complexes emerge as powerful tools for enantioselective catalysis.
