In order to obtain new fluorogens simple versatile methods of synthesis of some O-alkyl [(10-methylacridinium-9-yl)amino]methanethioate trifluoromethanesulfonates, O-alkyl [(10-methyl-10H-acridin-9-ylidene)amino]methanethioates and O-alkyl [(10-methyl-10H

9-Trifloxyacridinium salts 3a, b and 9,9'-oxy-bis(acridinium) salts 4a, b which are easily obtained from the 9-acridones 2a, b react readily with halides, pseudohalides and sulfur nucleophiles to give 9-substituted acridinium ions.This reaction represents an efficient alternative to the commonly used transformation of 9-chloroacridinium into other substituted acridinium salts; the two-step conversion of the carbonyl compound into a (pseudo)halide-substituted carbenium ion or into a thione may be generally applicable to ketones which can be transformed either into trifloxy carbenium ions or into dication ethers. - Keywords: Bis(acridinium) Ethers, 9-Substituted Acridinium Ions
