The novel complex cis ‐[(ITMe) 2 Pd(SiMe 3 ) 2 (ITMe=1,3,4,5‐tetramethylimidazol‐2‐ylidene) has been synthesized by mild oxidative cleavage of Me 3 SiSiMe 3 using [(ITMe) 2 Pd 0 ]. The use of this complex as precatalyst for the cis ‐bis(silyl)ation of alkynes using unactivated disilanes is reported.
