Silylium ions: from controversial beginnings to useful catalysts

Silylium ions can be very fleeting — so much so that their isolation was once considered impossible. This prevailing opinion was eventually challenged by chemists brave enough to conduct the challenging experiments that revealed silylium ions to not only be tractable but also synthetically versatile.
