Multinuclear magnetic resonance studies of the reactions of bidentate ligands with Pt(S2CNEt2)2. Comparisons with the reactions of Pt(S2P{OEt}2)2

The interactions in dichloromethane solution of Pt(S2CNEt2)2 with a number of potentially bidentate ligands have been studied by multinuclear (31P, 77Se, 195Pt) magnetic resonance techniques. The ligands used (L-L′) were Ph2PCH2CH2PPh2 (dpe), Ph2AsCH2CH2PPh2 (ape), Ph2PCH2PPh2 (dpm), Ph2PCH2P(E)Ph2 (E = S, Se to give dpmS, dpmSe), and Ph2AsCH2CH2P(E)Ph2 (apeS, apeSe). In 1:1 proportions the ligands dpe, ape, and dpm all eventually give [(η2-L-L′)Pt(η2-S2CNEt 2)]+. With dpe, the reaction is fast and no intermediate is observed; with ape, (η1-ape)Pt(η1-S2CNEt 2)(η2-S2CNEt2) is observable and kinetic and thermodynamic data for its conversion to the final product were obtained. The overall reaction with dpm is very slow and involves both (η1-dpm)Pt(η1-S2CNEt 2)(η2-S2CNEt2) and the dimer cis,cis-[Pt2(S2CNEt2) 2(μ-dpm)2]2+. In 1:2 proportions [(η1-L-L′)2Pt(η2-S 2CNEt2)]+ (L-L′ = ape, dpm) are formed but there is no further reaction in the dpe system. The relative instability of chelated ape and dpm is confirmed by reaction of [(η2-L-L′)Pt(η2-S2CNEt 2)]+ with PPh3 to give [(η1-L-L′)(PPh3)Pt(η2-S 2SNEt2)]+. The reaction between Pt(S2CNEt2)2 and dpmSe in 1:1 proportions is extremely complicated and is determined by the reactivity of the P=Se bond. The initial products include (η1-L-L′)Pt(η2-S2CNEt 2)(η2-S2CNEt2) (L-L′ = dpmSe, dpm) and dpmSe2. The reaction proceeds slowly to give cis,cis-[Pt2(S2CNEt2) 2(μ-dpm)2]2+ and [(η2-dpm)Pt(η2-S2CNEt 2)]+ that then react with the generated dpmSe2 to reinsert Se into a Pt-P bond to give [(η2-dpmSe)Pt(η2-S2CNEt 2)]+ as the final product. In contrast, dpmS reacts cleanly to give (η1-dpmS)Pt(η1-S2CNEt 2)(η2-S2CNEt2) and then [(η2-dpmS)Pt(η2-S2CNEt 2)]+ due to the lower lability of the P=S bond. No further reaction occurs with either ligand in 1:2 proportions. The ligands apeE do not react with Pt(S2CNEt2)2 in dichloromethane solution.
