Silyl tellurides reacted with alkylhalides under mild thermal conditions to give the corresponding alkyl tellurides and silylhalides in good to excellent yields. Substitution took place much faster in polar solvents, such as acetonitrile, than that in non-polarsolvents. After removal of the volatile silyl halides and solvent under vacuum, the essentially pure divalent organotellurium compounds were
A new method for the synthesis of 2,3-dialkylindoles is described. The silyltelluride-mediated coupling reaction of imines and 2-alkenylphenylisocyanides selectively occurred at the isocyanide moiety to give the corresponding imidoyltelluride. Tin hydride-mediated intramolecular cyclization of the imidoyltelluride affords 2,3-dialkylindoles in good to excellent combined yields.
