on the spectroscopic properties of their rhodium and iridium complexes was investigated. The new ligands Bn 2 NPSCH 2 CH 2 S a ( P - S a ) (Bn = benzyl, 4 ), Bn 2 NPSCHCHS a (CH 2 ) 3 C a H 2 ( P - S a )( C a - S a ) ( 6 ) and Bn 2 NP(4-XC 6 H 4 OMe) 2 (X = S, 7a ; X = O, 7b ) were converted to the rhodium and iridium complexes trans -[Rh(CO)Cl(L) 2 ] (L = 4 , 6 , 7 ), [RhCl(COD)(L)] (L = 4 , 6 , 7
摘要合成了亚磷酰胺配体的新硫衍生物,研究了硫单元对其铑和铱配合物光谱性质的影响。新的配体Bn 2 NPSCH 2 CH 2 S a(P-SA)(Bn =苄基,4),Bn 2 NPSCHCHS a(CH 2)3 C a H 2(P-SA)(C a-S a )(6)和Bn 2 NP(4-XC 6 H 4 OMe)2(X = S,7a; X = O,7b)转化为铑和铱配合物反式-[Rh(CO)Cl(L) 2](L = 4,6,7),[RhCl(COD)(L)](L = 4,6,7),[IrCl(COD)(7a)]和[IrCl 2 Cp ∗(6)] 。为了比较,还合成了这些制剂的一些亚磷酰胺配合物。光谱分析了新的金属配合物。对于羰基配合物,其v CO IR拉伸频率低于相应的亚磷酸酯和亚磷酰胺配体。具有新配体的铑配合物的1 J PRh耦合常数也小于相应的亚磷酰胺和亚磷酸盐配合物的1 J PRh耦合常数。最后,新配体的硒化物的1
