Silicon-transition-metal complexes halogen compounds

Whereas most of the known silylamines containing both a silicon halogen and nitrogen hydrogen unit undergo rapid condensation with HC1 elimination [11], transition metal substitution of the silicon provides unexpected high thermal stability. Compounds of this type are available via reaction of the dichlorosilyl complexes 18a-c with bulky primary amines to generate 19a-c (Eq. (4)). 

Transition-metal catalyzed metathesis of carbon-halogen bonds with Si-Si bonds provides useful access to organosilicon compounds. Most of the reaction may involve initial oxidative addition of the carbon-halogen bond onto the transition-metal followed by activation of the Si-Si bond to give (organosilyl)(orga-no)palladium(II) complex, which undergoes reductive elimination of the carbon-silicon bond.
