one-electron transfer oxidation of 2,2-dimethyl-2-silaindane by K5CoIIIW12O40 leads, in a slow step, to a radical cation which then undergoes fast C–Si bond cleavage, thus indicating that the rate of this cleavage is not significantly affected by the orientation of the C–Si bond with respect to the aromatic system.
K 5 Co III W 12 O 40的2,2-二甲基-2-silaindane的单电子转移氧化在一个缓慢的步骤中导致自由基阳离子,然后该阳离子经历快速的C-Si键裂解,从而表明C-Si键相对于芳族体系的取向对该裂解的速率没有显着影响。
