Reaction of tellurium with dichloromethane in the system hydrazine hydrate-alkali
摘要:
Tellurium reacts with dichloromethane in the system hydrazine hydrate-alkali substituting one chlorine atom by tellurium whereas the second chlorine atom undergoes reductive substitution by hydrogen leading to the formation of methyltellanyl derivatives. Tentative mechanism of reduction is discussed. The discovered reaction allows the preparation of organotellurium compounds containing the MeTe group, including those involving other chalcogens.
