The relative silatropic migration ability of SiMe3 and IndSiMe2 in (1-trimethylsilylindenyl) (indenyl)dimethylsilane and bis(1-trimethyl-silylindenyl)dimethylsilane was estimated by molecular orbital calculations. Data show similar barriers (25-26 kcal/mol) for the [1,5] sigmatropic shifts for these groups. The molecular structure of bis(inden-1-yl)dimethylsilane determined by X-ray diffraction and by B3LYP/6-31G(d) molecular orbital calculations show an almost orthogonal arrangement of the two indenyl groups.
