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.
