The kinetics of the reaction trans-^n- + L' <*> trans-^n'- + X (X=Cl^-, n=1, L=Me2SO, Et2S, PMe3, PEt3, PPh3, or AsEt3, L'=pyridine (py), Me2S, Et2S, PPh3, Me2SO, thiourea (tu), or NNN'N'-tetramethylthiourea (tmtu), n'=0; L'=Cl^-, Br^-, I^-, or SCN^-, n'=1; X=MeOH, n=0, L'=Cl^-, Br^-, I^-, or SCN^-, n'=1) have been studied in 95percent methanol and 5percent water at 25 deg C.The second-order rate constants, k₂, for the anionic substrates do not follow the usual dependence upon n⁰_Pt, the anionic nucleophiles being much less reactive than predicted.A new nucleophilicity scale, based on ^- as standard substrate, does give linear relationships for all the anionic substrates.The relationship between the nucleophilic discrimination and the nature of the trans ligand is discussed.
