A discrete ortho-lithiated acetophenone imine derivative: Isolation, characterization, and synthesis of group IV metal complexes

摘要

The reaction of a 3',4'-metliylenedioxyacetophellone imine (L-H; 1) with (BuLi)-Bu-n allows for the synthesis and isolation of a discrete ortho-lithiated imine (L-Li; 2). Through the use of salt metathesis pathways, this monoanionic, chelating N similar to C ligand has been employed to produce a series of titanium and zirconium complexes, including L2MX2 (M = Ti, X = Cl (5); M = Zr, X = Cl (3), CH2SiMe3 (4)) and L2Ti=(NBu)-Bu-t (6).
