Zirconium oxalates exist as compounds, double compounds, and mixed oxalato complexes (165,195,225—226). When the carboxylate ligand is a longer alkyl chain, the materials often are called zirconium soaps. [Pg.438]

Triphenylsulfonium tetrafluoroborate [(C6Hs)3 S" BF4 ] is used instead of diphenyl iodonium chloride to give phenyl radical as the initiating species. Potassium [tris(oxalato) cobaltate) (III)] with diphenyl iodonium chloride also has been used as the photoinitiator of acryl-... [Pg.251]

There is a wide range of diketonates, such as Ru(acac)3, with octahedral coordination [133b] (they do not seem, however, to be oxidized to the +4 state this is possible with osmium) similarly several salts of the tris(oxalato) complex Ru(C204)3 have been isolated. [Pg.51]

The reaction of the (necessarily) cis-oxalato complex with HCI in the last example, ensures the c/s-configuration for the chloro complex on recrystallization, the thermodynamically more stable fra s-isomer forms. fra s-Rupy4Cl2 has Ru-N 2.079 A and Ru—Cl 2.405 A. An imidazole complex (imH) tra s-[RuCl4(im)2] shows promise as a tumour inhibitor and is currently undergoing preclinical trials [135]. [Pg.51]

The strong Bronstedt acid nature of some hexacoordinated phosphorus derivatives, [7",H ] (Et20)4 in particular, was recently used within the context of an industrial application [36]. The conjugated acid of tris(oxalato)phosphate anion 7 was found to effectively catalyze the ring-forming reaction of trimethyl-hydroquinone 63 with isophytol 64 to give (all rac)-a-tocopherol 65 (ethylene-carbonate/heptane 1 1,100 °C, 90%, Scheme 19). This process is particularly... [Pg.28]

Polissar has observed 100 % exchange between Mn(III), as the oxalato ion Mn(Ox)J, and manganous sulphate. Adamson, using manganic chloride as the source of Mn(III), has observed the exchange to be incomplete in a time 15 sec with reactant concentrations 10 M. Both workers used a separation technique based on the precipitation of Mn(IV), present via the equilibrium... [Pg.92]

Of the various results, these appear to the reviewer to be the most meticulously obtained and they do not fit the other two rate laws suggested. At 25 °C n =. 0M perchlorate), = 5.10x10 l mole. sec" and = 4.78x10 l .mole" . sec . The corresponding reaction intermediates are a neutral chelate mono-oxalato complex and a (non-chelate) bis-oxalato complex of Cr(VI). [Pg.323]
