二甲基硅的环烷基(氨基)卡宾(cAAC)配位双自由基被分离为(cAAC)2 Me 2Si(1),(cAAC = C(CH 2)(CMe 2)2N-2,6-i-Pr 2C 6 H3),由Me 2SiCl 2在2当量的cAAC存在下用2当量的KC 8还原合成。在1当量cAAC存在下,1当量KCl 8还原Me 2SiCl 2,得到稳定的二甲基氯化硅单根(cAAC)Me 2SiCl(2)。
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).
