The reaction of the amidinato silylsilylene with a functionalized diaminochlorosilyl substituent, [LSiSi(Cl){(NtBu)₂C(H)Ph}] (1; L = PhC(NtBu)₂), with ArN═C═NAr (Ar = 2,6-iPr₂C₆H₃) in toluene afforded the delocalized hypervalent silyl radical [LSi^•(μ-CNAr)₂Si{(NtBu)₂C(H)Ph}] (2). It possesses a hypervalent silyl radical that delocalizes throughout the Si₂C₂ ring.
