Benzene thallium complex

Phosphonate Arene Osmium(II) Complexes. Benzene osmium(II) phosphonates have been made via the initial reaction of phosphite-containing osmium cations of type 147 with Nal. Demethylation occurs, and the anionic complex 182 is obtained. Protonation with trifluoroacetic afforded adduct 183 which generated complex 184 on treatment with pyridine. The latter was shown to be a precursor of the thallium complex 185 containing the chelating osmium phosphonate 115).

The molecular structure of decabenzylferrocene also helped to explain the rather low solubility of this compound in toluene or benzene, in sharp contrast with the previously found excellent solubility properties of other decabenzylmetallocenes and the pentabenzyl-Cp thallium and indium complexes in these solvents. The steric crowding of the benzyl groups in the ferrocene and their limited mobility leave little space for the solvent arene molecules to interact and subsequently to dissolve the molecule. This is quite similar to the situation encountered in the pentaphenylcyclopenta-dienyl derivatives with their closely packed phenyl rings (see Fig. 3). 

The most stable oxo-complexes are chelate compounds. Gallium and indium form tris- -diketone complexes, soluble in alcohol and benzene, and structurally similar to those of aluminium (Fig. 155). Gallium and thallium form trioxalato compounds like the oxalato-aluminates MJ[Ga ( 304)3]HgO. All the metals form tris-complexes with oxine (Fig. 156). 

The complexes 3 and 5 were transformed into the mixed sandwich complexes 6 by reaction with thallium cyclopentadienide in benzene and with sodium cyclopentadienide in ethanol, respectively. The structure was determined by X-ray crystallography. ... 

Antimony can be separated from bismuth by extraction into benzene from iodide medium. From 5 M H2SO4 and 0.05 M KI solution, Sbli is extracted in a good yield, whereas the bismuth complex is not extracted at all. Thallium is precipitated as T1(I) and separated by filtration [36]. Copper is masked with thiourea. 

Of the thallium halide complexes, the bromide complex is the most important in extraction separations. Tl(III) and Au(IlI) are extracted quantitatively from 1-3 M HBr with diethyl ether or DIPE, or MIBK. At that concentration of HBr, Fe(lII), Ga, In, Hg, and Te are extracted in small amounts. After extraction with MIBK, Ga, In, Fe(IlI), and Sn are stripped with a 1.5 iW HBr formamide solution, leaving only Tl(III) in the ketone phase [1]. The thallium(III) bromide eomplex has been extracted with TO A in benzene [2], or n-octylaniline in CHCI3 [3],...
