Abstract:

Ditertiarybutyltelluride is one of the best tellurium source compounds for the low temperature organometallic chemical vapor deposition of epitaxial films of mercury cadmium telluride. The known method of preparing ditertiarybutyltelluride is an inefficient, low yield process. Ditertiarybutyltelluride can be prepared in high yield by the reaction of tellurium tetrachloride and tertiarybutyllithium in tetrahydrofuran. The final product is isolated via vacuum distillation. An object of this invention is an efficient, high yield process for the preparation of ditertiarybutyltelluride as well as other diorganotelluride compounds.
