Synthesis and characterization of rhodium complexes containing atropisomeric sulfur ligands. Structure of [{Rh2(µ-L)(CO)3[P(OC6H4But-o)3]}2](H2L = 1,1′-binaphthalene-2,2′-dithiol)
摘要:
The addition of the atropisomeric racemic sulfur compound 1,1'-binaphthalene-2,2'-dithiol (H(2)L) to a dichloromethane solution of [{Rh(mu-OMe)(cod)}(2)] (cod = cycloocta-1,5-diene) afforded the dithiolate-bridged complexes [{Rh-2(mu-L)(cod)(2)}(n)] (n = 21 or 12). These reacted with carbon monoxide to give the dinuclear tetracarbonyl complex [Ru-2(mu-L)(CO)(4)] 3. The reaction of 3 with PR(3) provided the mixed-ligand complexes [{Rh-2(mu-L)(CO)(2)(PR(3))(2)}(2)] (R = Ph 4 or C(6)H(11)5) and [{Rh-2(mu-L)(CO)(3)(PR(3))}(2)] 6 [R = P(OC(6)H(4)Bu(t)-o)(3)]. The crystal structure of 6 was determined by X-ray diffraction.
