PGSE diffusion NMR studies on a series of mononuclear and dinuclear cationic platinum salts derived from (S)-MeO-Biphep and (R)-p-tolyl-BINAP are reported. The data show that (a) one can readily distinguish between mononuclear and dinuclear cations (b) the amount of ion pairing can be estimated qualitatively and (c) the charge delocalization rather than the amount of formal charge per metal cation is important for the position of the anion. The solid-state structure of the chloro-bridged salt, [Pt(μ-Cl){(S)-MeO-Biphep}]2(CF3SO3)2, is reported.

The zerovalent complexes Pt(diphos)(trans-stilbene) (diphos = dppe, dppf, (S,S)-Chiraphos, R-Tol-Binap, (R,R)-Me-Duphos, (S,S)-Diop) were prepared by reduction of the corresponding Pt(diphos)Cl2 compounds. NMR and crystal structure data show that the trans-stilbene complexes with chiral diphosphines exist as a mixture of diastereomers differing in their binding of the enantiofaces of the prochiral olefin; for R-Tol-Binap, they can be separated by recrystallization. The complexes Pt((R,R)-Me-Duphos)Cl2 and Pt(diphos)(trans-stilbene) (diphos = dppf, (S,S)-Chiraphos, R-Tol-Binap, (S,S)-Diop) were structurally characterized by X-ray crystallography.
