Tellurium-125 Moessbauer and NMR data for tetraphenyltellurium and bis(2,2'-biphenylylene)tellurium

The 125Te solution NMR chemical shifts of Ph4Te (508.9 ppm) and C12H8)2Te (486.3 ppm) have been measured at ambient temperature, together with the 125Te moessbauer parameters for the neat solids: Ph4Te (δ 0.09, Δ 5.60 mm s-1), (C12H8)2Te (δ 0.4

MECHANISM OF THE LITHIUM-TELLURIUM, LITHIUM-IODINE AND LITHIUM-MERCURY EXCHANGE REACTIONS: HYPERVALENT TELLURIUM AND IODINE ATE COMPLEXES

The lithium-tellurium exchange is among the fastest of the lithium-metalloid exchange reactions: only the lithium-iodine exchange is slightly faster.Tellurium, iodine and merury ate complexes are formed when diphenyl telluride, iodobenzene or diphenylmercury are treated with phenyllithium in THF.The mechanism of the lithium-tellurium exchange, (as well as the Li/I and Li/Hg) proceeds through such ate complex intermediates.Monomeric phenyllithium is the reactive form of phenyllithium (the dimer does not participate detectably).Tetraphenyltellurium and triphenyliodine also form hypervalent ate complexes under suitable conditions.

Mechanism of Thermal Decomposition of Tetra-aryltellurium Species

Tetra-aryltellurium species decompose upon heating giving good yields of diaryl tellurides and biphenyls.Radical-scavenging experiments show that phenyl radicals are not intermediates in the formation of biphenyls.In contrast, cross-over experiments give mixed biphenyls as well as mixed diaryl tellurides, but these are formed by a statistical redistribution of organic groups giving mixed tetra-aryltellurium species which decompose thermally in an indiscrimate fashion.
