Dimethylxanthene- and dibenzofuran-diamido complexes of titanium

The new ligands 4,5-dialkyl-and-diaryl-amido-9,9-dimethylxanthene and 4,6-dialkyl-and-diaryl-amido dibenzofuran serve as rigid, pre-organised and tunable ‘spectators’ for group 4 metals. The structure of a titanium complex with 4,5-di-cyclohexylamido-9,9-dimethylxanthene is reported.

Tridentate dialkylamido- and diarylamido-ligands based on the dimethylxanthene and dibenzofuran backbones have been synthesised and used to prepare titanium dialkylamides and alkyls.Figure optionsDownload as PowerPoint slide
