Abstract Dimethylsulfonium acetic acid betaine (1) and thiolanium acetic acid betaine (4) react with 4-nitrophenyldiazonium tetrafluoroborate (2) in aceticacid solution to give the formazyl compounds3 and5. Reaction of dimethylsulfonium- and thiolanium-trifluoroacetyl-methylide (9 and11, resp.) with compound2 leads to the phenylhydrazones10 and13, whereas trimethylammonium-trifluoroacetyl-methylide (14) reacts with formation of the formazane derivative15.
