Several metallictriflates and triflimides, among them anhydrous salts, were prepared in high yields underultrasonicactivation from the corresponding metal powders andstoichiometric amounts of triflic or triflimidic acid in different solvents. Different InIII and BiIII salts were tested as catalysts in hydrothiolation of olefins and in hydroarylation processes, respectively.

An efficient and versatile synthesis of indane, tetralin and benzosuberan derivatives has been developed; the synthesis starts from nonactivated aromatic compounds bearing unsaturated side chains and is a bismuth(III) or indium(III) trifluoromethanesulfonate-catalysed atom-economic process. A variety of polycyclic compounds have been isolated in high yields. Lactonisation could be observed for esters
