Preparation of an Active Neodymium Catalyst for Regioselective Butadiene cis-Polymerization Supported by a Dianionic Modification of the 2,6-Diiminopyridine Ligand

Treatment of the 2,6-diiminopyridine ligand 2,6-{[2,6-(i-Pr)2C6H3]NC(CH3)}2(C5H3N) with 2 equiv of Me3SiCH2Li afforded the corresponding {[2,6-{[2,6-(i-Pr)2C6H3]N-C(CH2)}2(C5H3N)]2- (1) dianion via deprotonation of the two methyl groups attached to the two imine functions. Reaction of 1 with NdCl3...
