WATER-SOLUBLE RUTHENIUM COMPLEXES CONTAINING TRIS(M-SULFONATOPHENYL) PHOSPHINE (TPPTS) - PREPARATION OF A SERIES OF [RU(H)(ETA(6)-ARENE)(TPPTS)(2)]CL COMPLEXES, [RU(H)(2)(CO)(TPPTS)(3)] AND REVISITED PROCEDURES FOR PREVIOUSLY DESCRIBED RUTHENIUM-TPPTS COMPOUNDS

The TPPTS ligand is the trihydrated form of the sodium salt of tris(m- sulfonatophenyl)phosphine. Complexes [Ru(Cl)(mu-Cl)(TPPTS)(2)](2) 1 an d [Ru(H)(X)(TPPTS)(3)], where X = Cl 2, OAc 3, have been prepared by a phosphine exchange from [Ru(Cl)(2)(PPh(3))(3)] and [Ru(H)(X)(PPh(3))( 3)] as previously described by Basset. Complex 1 presents in solution a solvolysis phenomenon which has been studied by P-31 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)(eta(6)-arene)(TPPTS)(2)]Cl 6, wher e arene = benzene, toluene, p-xylene, ethylbenzene, cumene, tetraline, cinnamic-, and dihydrocinnamic alcohols. All these compounds have bee n characterized by H-1, C-13, and P-31 NMR. Complexes 6 can also been obtained, but with an excess of TPPTS and sometimes OTPPTS, from RuCl( 3)d . 3H(2)O/n TPPTS, or from 2 and 3 as well.
