Five- and six-membered cyclic silylated onium ions of group 15 elementsIwere synthesized by intramolecular cyclization of transient silylium ionsII. Silylium ionsIIwere prepared by the hydride transfer reaction from silanesIIIusing trityl cation as hydride acceptor. It was found that smaller ring systems could not be obtained by this approach. In these cases tritylphosphonium ionsIVwere isolated instead. CationsIandIVwere isolated in the form of their tetrakispentafluorphenyl borates and characterized by multinuclear NMR spectroscopy and, in two cases, by X-ray diffraction analysis. Cyclic onium ionsIshowed no reactivity similar to that of isoelectronic intramolecular borane/phosphane frustrated Lewis pairs (FLPs). The results of DFT computations at the M05-2X level suggest that the strength of the newly formed Si–E linkage is the major reason for inertness ofI[B(C6F5)4] versus molecular hydrogen.
