The η 2 ‐iminotitanium complex 1 reacts with azobenzene in the presence of pyrrolidinopyridine py′ with ligand exchange to give the complex 2 , which transforms within several days at 100 °C into the phenylimidotitanium complex 3 . The length of the Ti‐N bond in 3 is 171.9(3) pm, and the Ti‐N‐C angle is 173.1(3)°. Unlike imidozirconium compounds, which readily react with C‐H activation, 3 is a “dead dog”—no reaction in benzene at 110°C! Ar′= 2,6‐ i Pr 2 C 6 H 3 , R 1 = t Bu.
