(aminopyrimidinato)titanium complex has been synthesised from inexpensive and easily accessible 2-(tert-butylamino)pyrimidine and [Ti(NMe2)4] and used as a catalyst for the intermolecular hydroamination of alkynes as well as the cyclization of aminoalkenes. The hydroamination reactions of 1-phenylpropyne and terminal arylalkynes deliver the corresponding anti-Markovnikov addition products with excellent yields and
