Abstract

Abstract Sodium hydrogen telluride reduces imonium salts effeciently at room temperature in ethanol. The products of the reaction depend upon the pH. Under alkaline pH only dihydro- derivatives are formed. Under acid pH (6-7) the products depend on the structure of the salt. The tellurium con be recovered quantitatively.
