摘要：

The η2‐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‐iPr2C6H3, R1 = tBu. (Figure Presented.)
