Synthesis, structure and catalytic activity of an air-stable titanium triflate, supported by an amine tris(phenolate) ligand

An air- and moisture-stable titanium(IV) triflate, 3, supported by a C-3-symmetric amine tris( phenolate) ligand has been synthesised, characterised by X-ray crystallography and demonstrated to be an excellent catalyst for formal aza-Diels - Alder reactions.
