✦ Synopsis

We have found that symmetrical benzene trisulfonic-acid trifluoride 1 is able to undergo nucleophilic addition at free positions on the aromatic ring. Its reactions with sodium sulfite, morpholine and carbanions of malonic and acetoacetic esters, dimedone and nitromethane lead to the formation of comparatively stable anionic r-complexes 3-8.

In the title molecule, C 24 H 18 O 3 S 3 , all bond lengths and angles are normal. The three thiophene rings make dihedral angles of 21.7 (3), 19.3 (7) and 4.8 (4) with the central benzene ring. The crystal packing is stabilized by weak intermolecular C-HÁ Á ÁO hydrogen bonds andinteractions.
