Stabilization of phosphorus in (1,2,3,4,5-pentaphenylphosphole)palladium

Our quantum chemical calculations predicted high stability of a palladium complex with 1,2,3,4,5-pentaphenylphosphole (ppp). The ligand, ppp, is unstable in free state and readily oxidized in air when in solution. The complex Pd(ppp) was synthesized and detected by electrospray ionization mass spect...

Summary:Our quantum chemical calculations predicted high stability of a palladium complex with 1,2,3,4,5-pentaphenylphosphole (ppp). The ligand, ppp, is unstable in free state and readily oxidized in air when in solution. The complex Pd(ppp) was synthesized and detected by electrospray ionization mass spectrometry. A Fourier transform ion cyclotron resonance mass spectrometry study revealed the presence of the complex in a solution after six months storage of the solution in air, thus demonstrating the possibility to stabilize the phosphorus ligand by complexation with transition metal.
