文摘

An insertion reaction of nitrosonium ion (NO⁺) into the metal鈭抍arbon bond of cyclometalated ruthenium(II) complexes is prepared with experimental evidence supporting a bimolecular direct NO⁺ insertion into the metal鈭抍arbon bond (i.e., M鈭扲 + NO⁺ 鈫?[M鈭扤(鈺怬)鈭扲]⁺) but not an intramolecular migratory insertion (i.e., R鈭扢鈭?NO) + L 鈫?L鈭扢鈭扤(鈺怬)R) as the reaction mechanism. Theoretical calculations suggest that the direct NO⁺ insertion into the M鈭扖 bond may be rationalized as a frontier orbital interaction between the [Ru鈭抋ryl]-dominated HOMO of the Ru(II) complexes and the LUMO of the NO⁺.
