A new simple and convenient synthetic route to organic chalcogenides R2Y (R = alkyl, allyl, benzyl; Y = Se, Te) is developed, which involves generation of Se2- and Te2- anions from Se and Te in the system KOH-hydrazine hydrate, where the latter plays the role of both the medium and reducing agent.Subsequent alkylation of the anions with the corresponding alkyl halides furnishes the target chalcogenides in almost 95percent yield.Alkyl chlorides react faster than alkyl bromides and alkyl iodides.

Sodium cleaves elemental tellurium, Tex, quantitatively to Te2-2 and Te2- in anhydrous tetrahydrofuran in the presence of catalytic amounts of naphthalene.Subsequent addition of alkylating agent affords dialkyl tellurides and dialkyl ditellurides in excellent yields.

Synthetic routes to alkylvinyl tellurides by direct reaction of metallic tellurium, acetylene and alkyl halide in the system KOH-SnCl2-H2O and successive interaction of divinyl telluride with lithium and alkyl halide in liquid ammonia have been developed.
REACTIONS OF CHALCOGENS WITH ACETYLENES. ALKYL VINYL TELLURIDES FROM TELLURIUM, ACETYLENE, AND ALKYL HALIDES
Gusarova, N. K.,Trofimov, B. A.,Tatarinova, A. A.,Potapov, V. A.,Sinegovskaya, L. M.,at al.
, p. 1686 - 1691 (2007/10/02)
Methods were developed for the synthesis of alkyl vinyl tellurides from metallic tellurium, acetylene, and alkyl halides in the KOH-SnCl2-H2O system and also by the successive action of lithium and alkyl halide on divinyl telluride in liquid ammonia.
