Iridium complexes pseudohalides

Other RhX(CO)(PPh3)2 compounds can be made as shown in Figure 2.23 metathesis with an alkali metal halide or pseudohalide is often convenient, but the most versatile route, as with the iridium analogues, is a two-stage process in which the fluoro complex is first prepared, the fluorine then being readily displaced. [Pg.100]

The arena of mononuclear carbonyl complexes of iridium is dominated by Vaska s compound, [IrCl(CO)(PPh3)2] (29), and its variants. The most conunon variation found in the literature comes from replacement of the chloride ligand with other monoanionic hgands such as halides and pseudohalides. Infrared spectroscopy has been used (by examining... [Pg.1858]

The iridium(III) complex [Ir(H)3(AsPh3)2(p-MeC6H4NC)] (99) is known to react with HX (or pseudohalides) to yield substitution products [lr(H)2(X)(AsPh3)(p-MeC6H4NC)i (X = Cl, Br, I, Nj). With carboxylic acids or pentane-2,4-dione, complex (99) yields the chelated complexes [Ir(L2)(AsPh3)(p-MeC6H4NC)] (L2 = carboxylate or pentane-2,4-dionate) in which Ir is reportedly reduced to 11. Reactions (52>-(60) reveal the utility of complex (99) in synthesizing complexes with iridium in various oxidation states. ... [Pg.1125]
