Abstract

An efficient synthesis of the earlier unknown trichloro- and tribromo(2-ahkoxy-2-phenylethyl)-λ4-tellanes with yields of 90 to 100% has been developed basing on alkoxytelluration of styrene with tellurium tetrachloride or tetrabromide in the presence of alcohols. The reduction of tellanes in the NaBH4-H2O-THF and Na2S2O5-H2O-C6H6 systems has afforded bis(2-alkoxy-2-phenylethyl)ditellanes in up to 95% yield.
