Synthesis of Organotellurium Compounds Based on Reactions of Polychloroethenes with Tellurium in the Hydrazine Hydrate–Alkali System

Key Points

• The aim is to synthesize organotellurium compounds by reacting polychloroethenes with tellurium.
• Reactions of polychloroethenes with tellurium in an alkali system
• Use of hydrazine hydrate and KOH as reagents
• Multicomponent reactions including dicholoromethane
• Formation of diethyl ditelluride from the reaction
• Synthesis of 1,3-ditellurole achieved with a yield of 30%
