Heterodialkylation of [Pt 2 (μ‐S) 2 (dppp) 2 ] (dppp=Ph 2 P(CH 2 ) 3 PPh 2 ) was achieved under high pressure (10 kbar). This enabled the synthesis of rare diplatinum complexes with structurally diverse thiolate bridges, such as [Pt 2 (μ‐SC 5 H 10 CO 2 CH 2 CH 3 )(μ‐SC 3 H 7 )‐(dppp) 2 ](PF 6 ) 2 , which was crystallographically identified. Complete homodialkylation was also achieved under similar conditions (6 kbar at room temperature), thus permitting the isolation of [Pt 2 (μ‐SC 2 H 4 CO 2 CH 2 CH 3 ) 2 (dppp) 2 ]‐(PF 6 ) 2 . The isolation of these complexes extends the applications of high‐pressure chemistry to thiolato homo‐ and heterobridged complexes that are otherwise not accessible.
