Popis: | A norbornene-based sulfide stabilized silylium ion 4 has been synthesized. The S-Si interaction was studied in solution and in the solid state by NMR spectroscopy and X-ray diffraction analysis as well as DFT calculations. Unlike the previously reported phosphine-stabilized silylium ion VII, behaving as a Lewis pair, calculations predict that 4 should behave as a Lewis acid toward acrylate derivatives. Indeed, the base-stabilized silylium ion 4 has emerged as an easy-to-handle silylium ion-based Lewis acid catalyst, particularly for the Diels-Alder cycloaddition, with poorly reactive dienes, and hydrodefluorination reactions. |
