coordinated to rhodium diolefine centres in the N,O-chelate bonding mode as shown by an X-ray structure determination of Rh(I)[( p -Tol)( p -TolN)CSO](NBD); triclinic space group P 1 with Z =4 and a = 9.314(2), b = 10.379(2), c = 23.170(3) A, α = 75.23(1)°, β = 75.83(1)°, γ = 65.37(2)°. The structure was solved to R = 0.042 for 7625 observed reflections. The (thioamido S-oxide)(diene)rhodium(I) complexes show
摘要由Rh(I)[(p- Tol)(对-TolN)CSO](NBD);Z = 4且a = 9.314(2),b = 10.379(2),c = 23.170(3)A,α= 75.23(1)°,β= 75.83(1)°,β=的三斜空间群P 1 65.37(2)°。对于7625个观察到的反射,将结构解析为R = 0.042。(硫酰胺基S-氧化物)(二烯)铑(I)配合物在溶液中表现出通量行为(质子和13 C NMR光谱法),包括二烯烃旋转通过四面体过渡态或形成五配位铑溶剂分子作为第五种配体的帮助。(硫代酰胺基S-氧化物)(二烯)铑(I)配合物与1的反应 2-双(二苯基膦基)乙烷(DPPE)得到的二聚化合物具有螯合键合的氨基磺胺和在两个Rh(I)中心之间桥接的DPPE配体。(硫代酰胺基S-氧化物)(二烯)-铑(I)配合物与一氧化碳的反应以螯合键合方式得到了与ph胺的单体1/1配合物。
