Reaction of 1,4-thiatellurin and some of its alkyl derivatives with n-butyllithium in tetrahydrofuran gives Z,Z-2,2′-dilithiodivinyl sulfide or alkyl derivatives and dibutyl telluride. With lithium diisopropylamide in tetrahydrofuran, in the case of 3,5′-dialkyl-1,4-thiatellurins, deprotonation with concomitant ring opening is the main reaction.
