Abstract

The cyclic alkyl(amino) carbene (cAAC) coordinated biradical of dimethylsilicon was isolated as (cAAC)₂Me₂Si (1), (cAAC = C(CH₂)(CMe₂)₂N-2,6-i-Pr₂C₆H₃), synthesized from the reduction of Me₂SiCl₂ using two equivalents of KC₈ in the presence of two equivalents of cAAC. The reduction of Me₂SiCl₂ by one equivalent of KC₈ in the presence of one equivalent of cAAC resulted in the stable dimethylsiliconchloride monoradical (cAAC)Me₂SiCl (2).
