The reaction of the amidinato silylsilylene with a functionalized diaminochlorosilyl substituent, [LSiSi(Cl){(NtBu)C(H)Ph}] (1; L = PhC(NtBu)), with ArN═C═NAr (Ar = 2,6-iPrCH) in toluene afforded the delocalized hypervalent silyl radical [LSi(μ-CNAr)Si{(NtBu)C(H)Ph}] (2). It possesses a hypervalent silyl radical that delocalizes throughout the SiC ring.
脒基硅硅烯与带有官能化二氨基氯硅烷基取代基的[LSiSi(Cl){(NtBu)C(H)Ph}](1;L = PhC(NtBu)),在甲苯中与ArN═C═NAr(Ar = 2,6 - iPrCH)反应,得到离域的高价硅自由基[LSi(μ - CNAr)Si{(NtBu)C(H)Ph}](2)。它具有一个在整个SiC环中离域的高价硅自由基。
