The rhodium and iridium complexes of dibenzothiophene (L) reveal an interesting case of linkage isomerism (91IC5046). Thus, the ti S) coordinated species [MCp LCb] on thermolysis with silver tetrafluoroborate afford the Ti -coordinated dicationic species. [Pg.47]

After extensive experimentation, a simple solution for avoiding catalyst deactivation was discovered, when testing an Ir-PHOX catalyst with tetrakis[3,5-bis (trifluoromethyl)phenyl]borate (BArp ) as counterion [5]. Iridium complexes with this bulky, apolar, and extremely weakly coordinating anion [18] did not suffer from deactivation, and full conversion could be routinely obtained with catalyst loadings as low as 0.02 mol% [19]. In addition, the BArp salts proved to be much less sensitive to moisture than the corresponding hexafluorophosphates. Tetrakis (pentafluorophenyl)borate and tetrakis(perfluoro-tert-butoxy)aluminate were equally effective with very high turnover frequency, whereas catalysts with hexafluorophosphate and tetrafluoroborate gave only low conversion while reactions with triflate were completely ineffective (Fig. 1).

The typical in situ reduction of the precursor [lr(COD)Cl]2 by molecular hydrogen under the same reaction conditions have been also performed in 1-n-butyl-3-methylimidazolium trifluoromethanesulfonate (BMl-CFsSOs) and 1-n-butyl-3-methylimidazolium tetrafluoroborate (BMl-BF [25]. The iridium nanoparticles prepared in BMTCF3SO3 and BM1-BF4 ILs, as previously observed with BM1-PF6, display irregular shapes with a monomodal size distribution (Figure 15.4). Mean diameters in the range of 2-3 nm were estimated with in situ TEM and small-angle X-ray scattering (SAXS) analyses of the lr(0) nanoparticles soluble in the ionic hquids, and by X-ray diffraction (XRD) of the isolated material. The mean diameters of iridium nanoparticles synthesized in the three ILs, as estimated by TEM, SAXS and XRD, are summarized in Table 15.1. [Pg.373]
