corresponding quinazolinone and urea derivatives under mild conditions using two titanium(IV) complexes [(ImRN)2Ti(NMe2)2] (R = tBu, 2a; R = Mes, 2b), which were synthesised by reacting tetrakis(dimethylamido)titanium(IV) [Ti(NMe2)4] with imidazolin-2-imine [ImRNH; R = tert-butyl (tBu) (1a), mesityl (Mes) (1b)] in a 1 : 2 molar ratio in toluene. Furthermore, the reaction of titanium complex 2a with 2,6-diisopropylphenylamine
