SELECTIVE REDUCTION OF IMONIUM SALTS BY SODIUM HYDROGEN TELLURIDE
Sodium hydrogen telluride reduces imonium salts efficiently 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 can be recovered quantitatively.
