  • Note di contenuto: The 1H NMR spectrum of Pt 2(η 1,η 2-C 3H 5) 2(acac) 2 has been examined and shown to be consistent with its solid state structure. Magnetization transfer measurements have shown pairwise exchange of the allylic protons, consistent with the platinum atoms reversing their bonding to each allyl group with Δ G ‡ 15.8 kcal mol −1. An equilibrium is slowly established with Δ G 23.0 kcal mol −1 and Δ G° 0.43 kcal mol −1 between the dimer and Pt(η 3-C 3H 5)(acac), which was not detected in the original work.
