Silylium Ions

  • Thomas MüllerEmail author
Part of the Structure and Bonding book series (STRUCTURE, volume 155)


The chemistry of silylium ions and related silyl cations is reviewed. The discussion is focused on work since 2005 with recourse on investigation since the early 1990s. Structural and spectroscopic aspects of silylium ions are emphasized. Included is also survey of methods for their preparation and of their applications in organic synthesis and catalysis.
