Resumen
The binuclear complexes [Rh2{μ-S(CH2)2S}(L2)2] [L2 = cycloocta-1,5-diene (cod) 1, L2 = (CO)2 2] and [Rh2{μ-S(CH2)2S}(CO)2(PR 3)2] (R = Ph 3 or OPh 4) have been prepared and oxidative addition of the electrophiles I2 and HgX2 (X = Cl or I) investigated. Compounds 3 and 4 undergo stepwise addition of molecular iodine to yield the symmetrical complexes [Rh2{μ-S(CH2)2S}In(CO) 2(PR3)2] [n = 2, R = Ph 5, R = OPh 6; n = 4, R = Ph 7, R = OPh 8]. However, interaction of 3 with HgX2 (X = Cl or I) affords the unsymmetrical compounds [Rh2{μ-S(CH2)2S}X2(CO) 2(PPh3)2] (X = Cl 9 or I 10). The crystal structure of 9 has been determined by X-ray diffraction methods.
