    • Just as difficult as the search for a stable silyl cation in condensed phases is the search for a proper name for this class of compounds, acceptable to all researchers involved. While silyl cations were named siliconium ions (which was consistent since carbenium ions were designated as carbonium ions at that time) in what is probably the first publication postulating a silicon analogue of a carbenium ion as an intermediate [F. C. Whitmore, L. H. Sommer, J. Gold, J. Am. Chem. Soc. 1947, 60, 1976-1977], this name is now commonly used for cationic silicon complexes with a coordination number higher than four. Since then the terms silylenium ion, silicenium ion, or silylium ion have been used for triply coordinated positively charged silicon compounds. The latter name is also suggested by IUPAC [G. J. Leigh, Nomenclature of Inorganic Chemistry, Blackwell Scientific Publishing, Oxford, 1990, p. 106]; alternatively, the term silyl cation is suggested.
