Systematic synthesis and crystal structures of tetraaryltellurium compounds Ar4TeIV

Hypervalent tetraaryltellurium(IV) compounds of the type Ar4TeIV(1: Ar = C6H5; 2: Ar = p-H3CC6H4; 3: Ar = p-t-BuC6H4; 4: Ar = p-F3CC6H4) were prepared via a convenient one-pot reaction between the isolated corresponding ArLi reagent and TeCl4. X-ray crystallographic analyses of 14 revealed distorted pseudo-trigonal-bipyramidal (TBP) structures for Ar4Te and the TBP character was analyzed by the dihedral angle method.

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.
