Investigations on non-classical silylium ions leading to a cyclobutenyl cation.

ABSTRACT: Instead of yielding the desired non-classical silylium ions, the reactions of different alkenes/alkynes with several [Me₃Si]⁺ sources mostly led to oligomerization, or - in the presence of Me₃SiH - hydrosilylation of the alkenes/alkynes. Yet, from the reaction of 2-butyne with ion-like Me₃Si-F-Al(OR^F)₃ (R^F = C(CF₃)₃) the salt of the silylated tetramethyl cyclobutenyl cation [Me₄C₄-SiMe₃]⁺[al-f-al]^- 1 ([al-f-al]^- = [(R^FO)₃Al-F-Al(OR^F)₃]^-) was obtained in good yield (NMR, scXRD, Raman, and IR).
