IAN-Amines: Direct Entry to a Chiral C2-Symmetric Zirconium(IV) β-Diketimine Complex Financial support has been provided by a GAANN Fellowship to S.B.C. (2001) and by Indiana University. IAN-amines are amines that are derived from Isoquinoline and 2-Amino Naphthalene.

(R-IAN)2ZrX2 complexes, where X = NMe2, Cl, have recently emerged as effective olefin polymerization precatalysts bearing chiral ligands formally of the β-diketimine class. An attempt to exchange dimethylamido ligands for alkyl (methyl) using the Jordan protocol resulted in a surprisingly facile transmetalation of the bidentate Me-IAN ligands from zirconium(IV) to aluminum(III). An initial study of
