Abstract

Reaction of Ln[N(TMS) 2 ] 3 with a stoichiometric amount of HL (HL = 3,5-Bu t 2 -2-(OH)-C 6 H 2 CH═N-8-C 9 H 6 N) at 40 °C resulted in the new complexes L′Ln(THF)·THF (Ln = Y(1), Yb(2); L′ = [3,5-Bu t 2 -2-(O)-C 6 H 2 CH═N-8- C 9 H 6 N 3,5-Bu t 2 -2-(O)-C 6 H 2 CH-(N)-8-C 9 H 6 N] 3− ) via metalation of a ligand quinoline ring in L 2 LnN(TMS) 2 formed in situ, followed by the attack of the newly formed aryl species at the imine group of the second ligand.
