Abstract:
Metal tellurolates (M = B3+; BuTeTeBu/NaBH4/EtOH; Li3+, Te0/BuLi/THF; In3+, BuTeTeBu/InI/EtOH) react with aminoalkynes to produce vinylic tellurides containing amino groups; the regio-, and stereo-chemistry of the hydrotelluration reaction depend on the metallic counter ion and on the nature of the amino group substituent.
