Delocalized Hypervalent Silyl Radical Supported by Amidinate and Imino Substituents
The reaction of the amidinato silylsilylene with a functionalized diaminochlorosilyl substituent, [LSiSi(Cl){(NtBu)(2)C(H)Ph}] (1; L = PhC(NtBu)(2)), with ArN=C=NAr (Ar = 2,6-iPr(2)C(6)H(3)) in toluene afforded the delocalized hypervalent silyl radical [LSi center dot(mu-CNAr)(2)Si{(NtBu)(2)C(H)Ph}] (2). It possesses a hypervalent silyl radical that delocalizes throughout the Si2C2 ring.
