Abstract
Cyclohexylsiloxy hydrides (e.g.,6) undergo intramolecular hydrosilatio n with significantly higher levels of stereochemical control (versus t heir dimethylsilyl counterparts such as 3). nle resulting spirocyclic silanes may serve as effective Lewis acids; association with a Lewis b asic site allows these entities to exist in the trigonal bipyramidal g eometry wherein ring strain is released.
