Synthesis of an [(NHC)(2)Pd(SiMe(3))(2)] Complex and Catalytic cis-Bis(silyl)ations of Alkynes with Unactivated Disilanes**

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.
