The compound is the precursor, upon deprotonation, to ansa-metallocene complexes within the area of transition metal indenyl complexes. Metals studied with 2,2′-bis(2-indenyl) biphenyl include titanium, zirconium, and hafnium.December 2016 The ligand and its complexes have been prepared by the research group of the late Brice Bosnich at The University of Chicago.10.1021/om00035a026 Ellis W.W.
