Abstract:

Organoselenium compounds are attractive synthetic targets because of their interesting biological activities as antioxidant and antifungal. Among organochalcogen compounds, the divinylic selenides and tellurides play an important role in organic synthesis because they are attractive as key intermediate in organic synthesis. In this context, our group has studied the use of renewable feedstocks in organic synthesis, following green and sustainable chemistry principles and as a continuation of our studies in this area, we report herein the selective preparation of divinylic selenides and tellurides starting from terminal aromatic alkynes and selenium or tellurium powder using NaBH4 as reducing agent and PEG-400 as solvent.
