A New Route to N ‐Silylated Diaminosulfanes: The Splitting of the Si Si Bond in Disilanes by Sulfur Diimides Sulfur diimides (R 1 N)S(N 2 ) (R 1 , R 2 = t Bu, SiMe 3 ; 1a–c ) and disilanes Cl 2 (R)Si–Si(R)Cl 2 [R = Me ( 2 ), Cl ( 3 )] react fast and quantitatively in a 1:1 ratio to give diaminosulfanes ( 4, 5 ) by cleavage of the Si–Si bond. The solid‐state structure of t Bu(SiMeCl 2 )N–S–N(SiMe 3 )SiMeCl 2 ( 4b ) has been studied both by X‐ray crystallography and 29 Si‐NMR spectroscopy.
