The 3,6-bis(trimethylsilyl)cyclohexadienyl radical (1), generated from the corresponding cyclohexadiene, gave the expected p-bis(tri-methylsilyl)benzene (4) at 0 deg.C.At 130 deg.C, however, the reaction afforded trimethylsilylbenzene, 4, and m-bis(trimethylsilyl)benzene in 62, 17, and 5percent yield, respectively.The suggested elimination of the trimethylsilyl radical from the cyclohexadienyl radical is demonstrated by ESR.
Diphenylphosphinophenolate: A ligand for the palladium-catalysed silylation of aryl halides activating simultaneously both palladium and silicon
Shirakawa,Kurahashi,Yoshida,Hiyama
, p. 1895 - 1896 (2000)
Diphenylphosphinophenolate was found to be an effective ligand for the palladium-catalysed silylation of aryl halides, activating not only palladium but also silicon of a disilane, where aryl bromides and iodides having such substituents as methyl, methoxy, amino, ethoxycarbonyl, trifluoromethyl, formyl or phenyl are applicable to the reaction with hexamethyldisilane to give the corresponding trimethylsilylarenes.

Rhodium-catalyzed silylation and intramolecular arylation of nitriles via the silicon-assisted cleavage of carbon-cyano bonds

supporting information; experimental part, p. 15982 - 15989 (2009/05/16)
A rhodium-catalyzed silylation reaction of carbon - cyano bonds using disilane has been developed. Under these catalytic conditions, carbon-cyano bonds in aryl, alkenyl, allyl, and benzyl cyanides bearing a variety of functional groups can be silylated. The observation of an enamine side product in the silylation of benzyl cyanides and related stoichiometric studies indicate that the carbon-cyano bond cleavage proceeds through the deinsertion of silyl isocyanide from η2-iminoacyl complex B. Knowledge gained from these studies has led to the development of a new intramolecular biaryl coupling reaction in which aryl cyanides and aryl chlorides are cross-coupled.
