Thallium(III) oxide as an oxidative reagent in organic chemistry

Oxidative properties of thallium(III) oxide in various organic reactions were studied. Oxidative bromination of organic compounds in Tl2O 3-KBr-trifluoroacetic acid system was carried out. New synthetic method for preparation of diphenylthallium salts from phenylhydrazine and thallium(III) oxide was developed.

Organothallium halides

When TlCl3 was reacted with cHexMgCl in THF, the triorganothallane TlcHex3 (1) could be obtained. The reaction of TlCl3 with PhLi in Et2O solution at 0 °C gave after workup the insoluble colorless solid Ph2TlCl (2). 2 was refluxed in pyridine. During cooling of the hot suspension colorless small crystals of [Ph2Tl(Py)2Cl]n (3) were formed. TlMes3 and TlCl3 in the molar ration 2:1 reacted in toluene at 20 °C to give the salt (TlMeS2)-[MesTlCl3] (4). The treatment of TlBr with MesMgBr solution (molar ratio 2:1) in THF/toluene lead to a suspension of MeSTlBr2 and Tl. The suspension was refluxed in pyridine. After cooling of the solution, colorless crystals of [MesTlBr2(Py)2]·Py (5) could be isolated. I and 3-5 were characterized by NMR and MS techniques and in the case of 3 by vibrational spectroscopy. In addition X-ray structure determinations of 3-5 were performed. According to this the structure of 3 can be understood in two ways: 3 consists of polymeric linear chains along [001] buildt-up by square planar [TlPh 4]- and [Tl(Py)4]3+ units connected by Cl- ions. This would mean a description as [{TlPh 4Cl}{Tl(Py)4CI}]n. The disorder phenomena in 3 would allow the second explanation, the formation of chains [Ph 2Tl(Py)2Cl]n. The unit cell of 4 contains zig-zag chains of four-membered rings consisting of linear (TlMes 2)+ units and distorted tetrahedrons of [MesTlCl 3]- ions. All chloro ligands in 4 are μ-bridging forming Tl2Cl2 four-membered rings and Tl-Cl-Tl sequences. In 5, molecular units of [MeSTlBr2(Py)2] are present. The thallium atoms possess a trigonal bipyramidal environment.

Organothallium compounds. Reaction of phenylhydrazine with thallium(III) oxide

Phenylhydrazine reacts with thallium(III) oxide in benzene to give organothallium compounds. Reactions of these compounds with acids afford diphenylthallium salts.

"Through-space" spin-spin coupling between thallium and hydrogen in o-alkylphenylthallium compounds

In this study a comparison was made of the Tl...H sidechain coupling constants for mono- and di-arylthallium derivatives in which a series of alkyl groups (CH3, C2H5, i-C3H7, t-C4H9) are 0- and p- to the thallium atom.The results provide evidence of "through-space" coupling between thallium and hydrogen in some of the o-alkylphenylthallium compounds, with the"through-space" contribution to 5J(Tl...C(CH3)3 in the o-tert-butylphenylthallium derivatives being considerable.
