Sodium and potassium carbamotelluroates [M(R 2 NCOTe), M = Na, K, Rb, Cs] were synthesized in moderate to good yields by reacting carbamoyl chloride with the corresponding alkali metal tellurides. The salts readily reacted with trimethylsilyl chloride to form O ‐trimethylsilyl carbamotelluroate (R 2 NCTeOSiMe 3 ), which further reacted with RbF and CsF to lead to the corresponding heavy alkali metal carbamotelluroates. These salts reacted with alkyl iodide and carbamoyl chlorides to give the corresponding Te ‐alkyl carbamotelluroates and dicarbamoyl tellurides in moderate yields.
