Zur Synthese gemischt substituierter Schwefeldiimide

Synthesis of mixed substituted sulfurdiimides Sulfurdiimides R? N?S?N? R ( 1 ) (R ? tBu or Me₃Si) react with potassium amide via transiminating forming the potassium salts R? N?S?N)^?K⁺ ( 2 ). Methatetical reactions of 2 with chlorides Me₃SnCl or Me₂SnCl₂ leads to the formation of the mixed subst. sulfurdiimides R? N?S?N? SnMe₃ ( 4 ) and (R? N?S?N)₂SnMe₂ ( 5 ), respectively.
