Abstract

Efficient methods for the preparation of trichloro- and tribromo(2-ethoxyalkyl)-λ⁴-tellanes in 80 to 100% yield have been developed on the basis of ethoxytelluration of hex-1-ene, hept-1-ene, and oct-1-ene with tellurium tetrahalides. Tribromo(2-ethoxyalkyl)-λ⁴-tellanes have been reduced to 1,2-bis(2-ethoxyalkyl)ditellanes in 92–95% yield with the system NaBH₄–H₂O–THF.
