The reaction of the NHC–disilicon(0) complex [(IAr)Si=Si(IAr)] (1, IAr=:C{N(Ar)C(H)}2, Ar=2,6‐iPr2C6H3) with two equiv of elemental Te in toluene at room temperature for three days afforded a mixture of the first dimeric NHC–silicon monotelluride [(IAr)Si=Te]2 (2) and its isomeric complex [(IAr)Si(μ‐Te)Si(IAr)=Te] (3). When the same reaction was performed for ten days, only 3 was isolated from the...
The trapping of a silicon(I) radical with N‐heterocyclic carbenes is described. The reaction of the cyclic (alkyl)(amino) carbene [cAACMe] (cAACMe=:C(CMe2)2(CH2)NAr, Ar=2,6‐iPr2C6H3) with H2SiI2 in a 3:1 molar ratio in DME afforded a mixture of the separated ion pair [(cAACMe)2Si:.]+I− (1), which features a cationic cAAC–silicon(I) radical, and [cAACMe−H]+I−. In addition, the reaction of the NHC–iodosilicon(I)...
