    The preparative use of the reaction between tris(2,6-dimethoxyphenyl)carbenium tetrafluoroborate and excess of an arylamine such as 4-methylaniline or 4-bromoaniline to yield firstly the aryl functionalised acridinium derivatives and then further in situ reaction to yield the desired functionalised triangulenium salts was found to be problematic. A preparative route for the triangulenium salts is presented along with a demonstration of the further derivatisation by a standard Suzuki coupling reaction. (C) 2002 Elsevier Science Ltd.
