Benzoyl phenyltelluride as highly reactive visible-light TERP-reagent for controlled radical polymerization
Benedikt, Stephan,Moszner, Norbert,Liska, Robert
, p. 5526 - 5531 (2014)
Benzoyl phenyltelluride (BPT) is a highly reactive TERP-reagent for visible-light-induced (400-500 nm) controlled radical polymerization. The compound can be easily prepared in one step from diphenyl ditelluride and benzoyl chloride. It shows a strong abs

Diaryl ditellurides were conveniently reduced by a system consisting of cerium trichloride and samarium intetrahydrofuran to produce the aryltellurolates. This "living" tellurolate anion species reacted smoothly with acid chlorides and acid anhydrides to

It was confirmed that lanthanum metal is an efficient reagent for the reductive cleavage of the tellurium-tellurium bond of ditelluride. Alkyl phenyl tellurides were prepared by the reaction of diphenyl ditelluride with primary and secondary alkyl halides

Simple preparation of aryl telluroesters from reaction of tellurium powder and aryl Grignard reagents then acylation with acyl chlorides. Addition of telluroesters to arylpropiolates gave (2Z)-β-aryltelluro-α,β-unsaturated esters with high stereoselectivity.
Reductive cleavage of Se-Se and Te-Te bond by samarium diiodide: Synthesis of selenoesters, telluroesters, unsymmetrical alkylphenyl selenides and tellurides
Zhang,Yu,Lin
, p. 189 - 193 (2007/10/02)
The reduction of diaryl diselenides and ditellurides by samarium diiodide led to samarium arylselenolates and samarium aryltellurolates respectively (ArSeSmI2 and ArTeSmI2). These species reacted smoothly with acyl halides and alkyl

Diaryl Diselenides react with CO(5-100 atm) at 100-200°C during 1-4 h in the presence of Co2(CO)8 to give the corresponding aryl selenocarboxylic acid esters in 21-96% yields. Similar treatment of diphenyl ditelluride gives the telluro analogues in lower yields. Didodecyl diselenide also gives the corresponding seleno ester, while esters were not produced from dibenzyl diselenide and didodecyl ditelluride. Under milder conditions (10 atm CO/125°C/1 h) the reactivity of (PhM)2 (M S, Se, Te) for the corresponding esters was found to be in the order Te > Se > S. The carbonylation of diaryl diselenides proceeds catalytically in Co2(CO)8 in the presence of triphenylphosphine. It was shown unambiguously that benzoylcobalt tetracarbonyl, which is one of the possible intermediates when aryl is phenyl, reacts smoothly with diphenyl diselenide or ditellutide to give the corresponding ester, phenyl selenobenzoate or tellurobenzoate, respectively, in a good yield.

SYNTHESIS AND PROPERTIES OF TELLURIUM(II) COMPOUNDS: DIARYLTELLUROESTERS, ArCOTeEAr'
Gardner, Sylvia A.,Gysling, Henry J.
, p. 111 - 122 (2007/10/02)
A series of organotellurium(II) derivatives of the general formula ArCOTeAr' (Ar,Ar'=phenyl, p-tolyl, p-anisyl, p-bromophenyl, p-trifluoromethylphenyl, 1-naphthyl) have been prepared and characterized chemically and spectroscopically.Various chemical reactions of this class of compounds have been investigated, and the reaction of these compounds with (PhCN)2PdCl2 to give the polymeric (Pd(TeAr')2)n derivatives suggests that these organotellurium reagents may be useful precursors of TeAr'- ligands in reactions with transition-metal substrates.
