Amine elimination synthesis of a titanium(IV) N-heterocyclic carbene complex with short intramolecular Cl•••Ccarbene contacts

The reaction of 1,3-dimesitylimidazolium chloride with Ti(NMe2)(4) results in the 1,3-dimesitylimadazol-2-ylidene complex of Ti(NMe2)(2)Cl-2 (3); the X-ray crystal structure of 3 evidences short intramolecular Cl...C-carbene contacts.
