Metal complexes synthesis and properties

The TPPTS ligand is the trihydrated form of the sodium salt of tris(m-sulfonatophenyl)phosphine. Complexes [Ru(Cl)(μ-Cl)(TPPTS)2]21 and [Ru(H)(X)(TPPTS)3], where X = Cl 2, OAc 3, have been prepared by a phosphine exchange from [Ru(Cl)2(PPh3)3] and [Ru(H)(X)(PPh3)3] as previously described by Basset. Complex 1 presents in solution a solvolysis phenomenon which has been studied by 31P NMR. Complex 1 is a useful starting material to easily prepare 2, [Ru(H)2(TPPTS)4] 4, the new species [Ru(H)2(CO)(TPPTS)3] 5, and the series of the new water-soluble complexes [Ru(H)(η6-arene)(TPPTS)2]Cl6, where arene = benzene, toluene, p-xylene, ethylbenzene, cumene, tetraline, cinnamic-, and dihydrocinnamic alcohols. All these compounds have been characterized by 1H, 13C, and 31P NMR. Complexes 6 can also been obtained, but with an excess of TPPTS and sometimes OTPPTS, from RuCl3 · 3H2On TPPTS, or from 2 and 3 as well.
