Structure and Reactivity of Ag(I) Complexes Bearing Tridentate Phosphinine Ligands

Structure and reactivity of novel Ag(I) complexes with tridentate phosphinine (phosphabenzene) ligands are discussed in this article. An equilibrium between the dimer and the monomer was observed for the λ3-phosphinine Ag(I) complex in the solution state. The λ3-phosphinine Ag(I) complex can be oxidized by PhI(OAc)2 to afford λ5-phosphinine species, maintaining the coordination to the metal center. Photochemical properties of the Ag(I) complexes were also investigated, and the emission of the λ3-phosphinine Ag(I) complex showed solvatochromic behavior.
