Mono-coordinated silicon(II) cations are predicted to be reactive ambiphiles, combining the typically high Lewis acidity of silicon cations with nucleophilicity due to the presence of an electron pair at the same atomic centre. Here, a carbazole-derived scaffold was used to isolate salts with a mono-coordinated silicon(II) cation, [RSi]<sup>+</sup> (R=bulky carbazolyl substituent), by halide abstraction from a base-free halosilylene, RSiI, with Ag[Al(O<sup>t</sup> Bu<sup>F</sup> )<sub>4</sub> ]. ...[more]
