How can the Metal Affect the Proton Transfer to the Dihydrides [P{(CH2CH2PPh2)3}MH2 (M = Fe, Ru, Os)? A Low-Temperature Electronic Spectroscopy Study

This work reports an account of our studies of the protonation of the dihydrides [(PP3)MH2], [PP3 = P(CH2CH2PPh2)3; M = Fe (1), Ru (2), Os (3)] and highlights the great potential of electronic spectroscopy in investigating the proton transfer reactions as well as elucidating the influence of the metal in this process.
