[1,5]-Silatropic shifts in disilyl substituted indenes: an NMR spectroscopic and computational study

The equilibrium profiles for [1,5]-silatropic shifts in a series of 1,3-/1,1-disilyl substituted indenes were studied by NMR and computational methods based on density functional theory. Both methods indicate higher activation parameters for the [1,5]-shifts than observed in monosilyl substituted indene analogues.
