Synthesis of chelating ditelluroether ligands, RTeCH2CH2CH2TeR (R = Me, Ph)

Hope, Eric G.,Kemmitt, Tim,Levason, William

, p. 206 - 207 (1987)

RTeLi (R = Me, Ph), prepared in situ in tetrahydrofuran from RLi and Te, react at low temperatures with 1,3-dihalopropanes, X(CH2)3X (X = Cl, Br), to give high yields of RTe(CH2)3TeR. At ambient or higher temperatures these reactions yield mainly R2Te2. The RTeCH2TeR are made analogously, but 1,2-dichloroethane gave only R2Te2.
