Synthesis and structures of heterobimetallic Ir 2 M (M Pd, Pt) sulfido clusters and their catalytic activity for regioselective addition of alcohols to internal 1-aryl-1- …
The heterobimetallic trinuclear sulfido clusters [(Cp* Ir) 2 (μ3-S) 2MCl2](M= Pd (3), Pt (4); Cp*= η5-C5Me5) were synthesized from the dinuclear hydrogensulfido complex [Cp* IrCl (μ- SH) 2IrCp* Cl](2) and [MCl2 (COD)](COD= cycloocta-1, 5-diene), while the reaction of 2 with [Pd (PPh3) 4] afforded the cationic trinuclear cluster [(Cp* Ir) 2 (μ3-S) 2PdCl (PPh3)] Cl (5). Clusters 3 and 4 reacted with PPh3 to give a series of mono and dicationic clusters ...
