Abstract
Cationic bis-areneruthenium complexes with bridging thiolato and hydride ligands were prepd. and characterized. The cationic complexes [(?-H)[Ru(?6-arene)]2(?-4-XC6H4S)2]+ and [(?-H)2[Ru(?6-arene)]2(?-4-XC6H4S)]+ (arene = 1,2,4,5-Me4C6H2 or C6Me6; X = Br, Me) were prepd. in good yields by stepwise substitution of hydride ligands in [(?-H)3[Ru(?6-arene)]2][BF4] by thiophenols 4-XC6H4SH. The dibromo deriv. [(?-H)[Ru(?6-C6Me6)]2(?-4-BrC6H4S)2]+ undergoes Suzuki coupling with 3-thiopheneboronic acid to give [(?-H)[Ru(?6-C6Me6)]2[?-4-[3-(C4H3S)C6H4S-?S]2]]+. This dibromo complex is a potential precursor for the insertion of dinuclear hydrido organometallic moieties in the main chain of conjugated mols. [on SciFinder(R)]
