The barriers to trimethylsilyl migrations in indenes and benzindenes: Silatropic shifts via aromatic transition states
Abstract
The barriers to migration of a trimethylsilyl group around the five-membered ring of indene, and of linear and angular benzindenes, have been calculated at the unrestricted Hartree-Fock (UHF) level of theory by using AMPAC and MOPAC. It is found that the retention of aromatic character in the transition state and in the intermediate isoindene lowers the barrier for the silatropic shifts. A preliminary experimental study on a trimethysilyl …
