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. Although early reports on the existence of silylium ions were met with controversy, we now know how to stabilize silyliums and exploit them as powerful catalysts and reagents.

硅离子：从有争议的开始到有用的催化剂

硅离子可能非常短暂-如此之大，以至于它们之间的隔离曾经被认为是不可能的。最终，这种普遍的观点遭到化学家的挑战，他们足够勇敢地进行具有挑战性的实验，结果表明硅离子不仅易于处理，而且具有合成用途。尽管有关硅离子存在的早期报道引起争议，但我们现在知道如何稳定硅离子并将其用作强大的催化剂和试剂。
