Summary:[TiO(salen)]n polymers are solubilised in aldehyde solution giving highly reactive entities. Unprecedented carbon‐based chemistry is demonstrated by the formation of new ligands about the titanium centre. Identified by X‐ray crystallography are a polymer deconstructed [Ti(salen)] oxo dimer, a [Ti(salen)] catecholato complex and an unusual [Ti(salen)] diolato complex. Formation of the new ligands appears to be related to the salicylidene ligand aromatic ring ortho substituent and the aldehyde used. [TiO(salen)]n polymers solubilised in aldehyde solution show potent activity when ortho substituents are present on the salicylidene ligand aromatic rings. Unprecedented carbon‐based chemistry is demonstrated by the formation of new ligands about the titanium centre.
