Abstract

<jats:p>S-Perfluoroalkyl-N-pentafluorosulphanyl sulphurmonofluoride imides <jats:inline-formula><jats:alternatives><jats:inline-graphic xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="graphic/Untitled-1.jpg" /></jats:alternatives></jats:inline-formula> (Rt - CF<jats:sub>3</jats:sub> (1a) , t-C<jats:sub>3</jats:sub>F<jats:sub>7</jats:sub> (1b)) are prepared by the reaction of NSF<jats:sub>3</jats:sub> with appropriate sulphurtrifluoride derivatives. The fluorine bonded to sulphur(IV) in 1a and 1b is substituted by PCl<jats:sub>5</jats:sub> to give sulphurmonochloride imides <jats:inline-formula><jats:alternatives><jats:inline-graphic xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="graphic/Untitled-2.jpg" /></jats:alternatives></jats:inline-formula> (Rt = CF<jats:sub>3</jats:sub> (2a), i-C<jats:sub>3</jats:sub>F<jats:sub>7</jats:sub> (2b)). The chlorine in 2a and 2b can be exchanged by reaction with suitable silver(I) and mercury(II) salts.</jats:p>
