The rate of enantiomerization of the racemic α-phenylselenoalkyllithium compound 6 has been determined by dynamic NMR spectroscopy in THF.The enantiomerization rate was found to be first order with respect to monomeric 6 and to show no conspicuous sol

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.
