Darstellung der ersten Sulfin‐imide (Thion‐<i>S</i>‐imide) mit Perfluormethylgruppen unter Verwendung von Natrium‐hexamethyldisilazanid als schonendes Dehydrohalogenierungsreagenz

Preparation of the First Thione S‐Imides with Perfluoromethyl Groups by the Use of Sodium Hexamethyldisilazanide as a Mild Dehydrohalogenation Reagent From the reaction of the sulfenyl chloride 1 with the monosilylated amines 2a , b the sulfenamides 3a , b are obtained in good yields. 1,3‐Dehydrohalogenation of 3a , b with sodium hexamethyldisilazanide yields the thione S ‐imides 5a , b . Imide 5a reacts with norbornene ( 6 ) to produce the isothiazolidine derivative 7 . The structures of 5b and 7 are confirmed by X‐ray analyses.
