    Summary
    The cationic complexes Ru2[(p-MeC6H4iPr)2(p-SC6H4Br)3]+ and Rh2 [(C5Me5)2(p-SC6H4Br)3]+ are available in quantitative yields from the reaction of p-HSC6H4Br with [Ru(p-MeC6H4iPr)Cl2]2 and [Rh(C5Me5)Cl2]2 respectively. These complexes are found to undergo triple Suzuki coupling with oligophenylene boronic acids to give [Ru2 (p-MeC6H4iPr)2{p-S-(C6H4)n-C6H5}3]+ and [Rh2(C5Me5)2{p-S-(C6H4)n-C6H5}3]+ respectively. The star-like trisbromo complexes are potential precursors for the insertion of dinuclear organometallic entities into the main chain of conjugated molecules.
