Abstract
A new family of delocalized lipophilic cations containing one to three carbimino, sulfimino and phosphinimino units with Cl−, Br−, HF2− and Me3SiF2− as counterions has been designed. The compounds synthesized demonstrate high performance and thermal stability in the ‘Halex’ fluorination reactions. For the first time sulfur tetrachloride pregenerated at −78°C was successfully applied in reactions with N-nucleophiles to afford straightforwardly sulfonium chlorides with three S–N bonds.
