The tert-butylimido complex [Ti(NBu(t))Cl-2(py)(3)] 1a (py = pyridine) undergoes exchange reactions of the NBu(t) ligand with arylamines RNH(2) to form the arylimido derivatives [Ti(NR)Cl-2(py)(3)] (R = C(6)H(4)Me-4 1b, C6H4NO2-4 1c or C(6)H(3)Me(2)-2,6 1d); comparison of the crystal structures of 1a-1c gave a direct evaluation of N-substituent effects in d(0), six-co-ordinated organoimido complexes.
