Abstract

Heterodialkylation of [Pt₂(μ-S)₂] (dppp = Ph ₂P(CH₂)3PPh₂) was achieved under high pressure (10 kbar). This enabled the synthesis of rare diplatinum complexes with structurally diverse thiolate bridges, such as [Pt₂(μ-SC ₅H₁₀CO₂CH₂CH₃)(μ- SC₃H₇)-(dppp)₂](PF₆)₂, which was crystallographically identified. Complete homodialkylation was also achieved under similar conditions (6 kbar at room temperature), thus permitting the isolation of [Pt₂(μ-SC₂H₄CO ₂CH₂CH₃)₂(dppp)₂]- (PF₆)₂. The isolation of these complexes extends the applications of high-pressure chemistry to thiolato homo-and heterobridged complexes that are otherwise not accessible.
