The addition of the atropisomeric racemic sulfur compound 4,4′-biphenanthrene-3,3′-dithiol (H2 biphes) to a dichloromethane solution of [M(μ-OMe)(cod)}2] (M = Rh, Ir, cod = cycloocta-1,5-diene) afforded the dithiolate-bridged complexes [Rh2(μ-biphes)(cod)2}n] (n = 2 5 or n = 1 6) and [Ir2(μ-biphes)(cod)2}n]·nCH2Cl27. When 1,1′-binaphthalene-2,2′-dithiol (H2 binas) reacted with [Ir(μ-OMe)(cod)}2]
将阻转异构的外消旋硫化合物4,4'-联菲-3,3'-二硫醇(H 2 biphes)添加到[M(μ- OMe)(cod)} 2 ]的二氯甲烷溶液中(M = Rh, Ir,cod =环辛-1,5-二烯)得到二硫醇盐桥联的配合物[Rh 2(μ- biphes)(cod)2 } n ](n = 2 5或n = 1 6)和[Ir 2(μ- biphes)(cod)2 } n ]· n CH 2 Cl 2 7。当1,1'-联萘-2,2'-二硫醇(H2个BINAS)与[的Ir(μ -OMe)(COD)} 2 ],配合物[Ir 2(μ -binas(COD))2 ] 8获得。配合物5和6与一氧化碳反应,得到二核四羰基配合物[Rh 2(μ- biphes)(CO)4 ] 9。9与PR 3的反应提供了混合配体络合物[Rh 2(μ- biphes)(CO)2(PR 3)2 } 2 ]· xCH 2 Cl
