Polymerization of methyl methacrylate catalyzed by nickel complexes with hydroxyindanone-imine ligands†
Abstract
A series of new hydroxyindanone-CC2H3(CH3)C6H2(CH3)OH] (HL111) and [ArN
CC2H3(CH3)C6H2(R)OH] (Ar = 2,6-i-Pr2C6H3, R = Me (HL222), R = H (HL333), and R = Cl (HL444)) were synthesized and characterized. Reactions of hydroxyindanone-
CC2H3(CH3)C6H2(CH3)O]6 (1) and the mononuclear bis(indanone-iminato)nickel(II) complexes Ni[ArN
CC2H3(CH3)C6H2(R)O]2 (Ar = 2,6-i-Pr2C6H3, R = Me (2), R = H (3), and R = Cl (4)). All nickel complexes were characterized by their
