Indium(III) trifluoromethanesulfonate was found to be an excellent catalyst for the highly regioselective intra- and intermolecular addition of thiols to non-activated olefins and could be recycled and reused without loss of activity.

Lithiation and trapping at convenient temperatures (0/−10 °C) of five cyclicsulfides such as tetrahydrothiophene, tetrahydrothiopyrans and a thiomorpholine enables straightforward α-functionalisation. Trapping with a wide range of electrophiles generates more than 50 diverse α-substituted saturated sulfur heterocycles that are not easily synthesised by the currently available methods. TMEDA=N,N,N′
