Indium(I) Iodide-Mediated Chemo-,Regio-, and Stereoselective Hydro­telluration of 2-Alkyn-1-olDerivatives

Abstract

Indium(I) iodide promotes the rigorous chemo-, regio-, and stereoselectivehydrotelluration of 2-alkyn-1-ol derivatives with diphenylditelluride.The Markovnikov adducts with stereochemistry corresponding to an anti addition of the tellurol constituentsacross the triple bond were obtained in good yields.

Key words

indium(I) iodide - vinylic tellurides - hydrotelluration - Markovnikov addition - stereoselectivity

Compound 1 ishighly air-sensitive, and decomposes producing the correspondingditelluride. We have not attempted to isolate it, and its formationis based on the analogous production of IIn(EC₆H₅)₂,E = S, Se. [6]
