Abstract The new series of iridium compounds of the type IrHX 2 T, where X = Cl, Br and T = ( o -Ph 2 LC 6 H 4 ) 2 L′ as TP (L = L′= P); PDAS (L = As, L′ = P); ASDP (L = P, L′ = As); TAS (L = L′ = As) have been prepared and characterized (only in the X = Br, T = TAS case was the complex IrBr 3 TAS obtained instead). The nature of these products has been investigated by i.r. spectroscopy and their stereochemistry
摘要一系列新的铱化合物,类型为IrHX 2 T,其中X = Cl,Br和T =(o -Ph 2 LC 6 H 4)2 L'为TP(L = L'= P);PDAS(L = As,L'= P); ASDP(L = P,L'= As); 已经制备并表征了TAS(L = L'= As)(仅在X = Br,T = TAS的情况下才获得了复杂的IrBr 3 TAS)。这些产品的性质已通过红外光谱进行了研究,并根据1 H和31 P nmr光谱分析确定了它们的立体化学。有证据表明,由于苯基的拥挤,基于子午结构,总是优选具有子午线结构的异构体。在相同的制剂中还观察到其他氢化铱,可能是离子氢化物,但由于其不稳定性而未被鉴定。
