SELECTIVE REDUCTION OF IMONIUM SALTS BY SODIUM HYDROGEN TELLURIDE

Article abstract of DOI:10.1016/S0040-4039(00)89225-4

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.
