摘要

Abstract Several sulfur-bridged heterocyclic carbocations of the acridinium and triangulenium family were prepared using 9-(2, 6-dimethoxyphenyl)-1, 8-dimethoxy- thioxanthenium tetrafluoroborate [7][BF 4] as key synthetic intermediate. Thanks to simple yet not so facile aromatic nucleophilic substitution reactions, thiachromenoacridinium, azaoxa-and dioxathiotriangulenium salts (eg,[8][BF 4],[9][BF 4], and [10][BF 4], respectively ...
