An air and moisturestable C3‐symmetric titanium(IV) triflate, supported by a tripodal amine‐(tris‐phenolate) ligand, has been synthesized and characterized by X‐ray crystallography and shown to be a good Lewisacidcatalyst for a range of aza‐Diels–Alder, Diels–Alder, syn aldol, allylation, and alkylation reactions.
