Synthetic efforts to attach aryl-oxazoline chelates to first-row transition metals featured heterolytic CH bond activation, oxidative addition, and aryl anion equivalents, but only the latter two methods were productive, yielding [{κ-C, N-(o-C6H4) CMe2 (COCH2CMe2N)} Cr] 2 (μ-Cl) 2 (6 2),{κ-C, N-{(o-C6H4) CMe2 (COCH2CMe2N)} Fe (py) Cl (7), and {κ-C, N-(o- C6H4) CMe2 (COCH2CMe2N)} 2Ni (9), for example.
