Halogen-substituted silylium ions are among the strongest known Lewis superacids with promising synthetic applications, but their synthesis has not been possible using established methods for generating silicon cations. Now, a general approach to these elusive reactive intermediates is reported, based on the protonation of halosilanes with a Brønsted superacid.
