Synthesis and structures of titanium complexes bearing tetradentate tripodal [O2XC] ligands (X = C, P)†
Abstract
We report the synthesis and structures of titanium complexes supported by tripodal mixed-donor [O2CC] and [O2PC] ligands. Stepwise cyclometallation of a chelating bis(phenoxide) complex led to tetradentate binding of the [O2CC] ligand to the titanium center. Phosphination of a Ti–C bond of the [O2CC] complex afforded the tripodal [O2PC] ligand.
