Abstract

A new chloronium-containing salt, [Me2 Cl][Al(OTeF5 )4 ], was synthesized on multigram scale by means of a simple one-pot procedure. The isolated product can be handled at room temperature and used as a strong electrophilic methylation agent. This is demonstrated by the methylation of the very weak bases P(CF3 )3 , PF3 , MeI, and MeBr.
